Ivan MolodetskikhOne cool thing I noticed about true maximize is that apps like GIMP or Inkscape or Blender, that really want all available space, maximize themselves at startup, so you don't have to window-rule them manually in your config

Ivan MolodetskikhSmall change on niri-git for people using the foot terminal with CSD, or other apps that constrain their sizes to a grid: niri will now match the default column width to a preset width when a window opens. So opening foot sized "proportion 0.5" and then pressing Mod+R will switch you to the next preset width, even if foot actually opened slightly smaller to match its terminal grid. Before the change, the first Mod+R would pick the same "proportion 0.5" in this case and "do nothing".

Ivan MolodetskikhAlso, experimenting with this interaction tweak on a branch: what if dragging tiled windows horizontally scrolled the view instead of dragging them "out"? This makes it possible to scroll the view mouse-only without going through the Overview (the zooming gets quite tiring when it's frequent), and makes it possible to scroll the view touch-only. To drag the window out of the layout, you can still drag it downward.

Ivan MolodetskikhAdded a small "Quick Start" to the niri docs that gets you going with niri + DMS in three commands:
https://yalter.github.io/niri/Getting-Started.html#quick-start
Tested the Fedora ones on a fresh VM, worked out nicely, getting me into a session with a very functional desktop shell.
#niri
Ivan MolodetskikhCurrently in the middle of finishing up the Alt-Tab PR for niri: https://github.com/YaLTeR/niri/pull/1704
Got most things working as I'd like, though still plenty of fixes and clean-ups left. Fully live window previews with block-out-from support and fading title labels.
There's some interesting design differences compared to other desktops: on niri I expect it's common to have multiple terminals open, so Alt-Tab must go by windows (not by apps) and must show previews big enough to pick the right one.

Ivan MolodetskikhJust merged Alt-Tab to main, shortly arriving at your nearest niri-git. Comes with plenty of ways to tweak it if you want [1], and a focus timestamp in the IPC [2] that lets shell devs make their own recent windows switchers.

Ivan MolodetskikhDid some work on the TTY backend in niri over the past few days. Merged PR for DisplayLink dock support, added "panel orientation" property read, and, based on cosmic-comp code, implemented the necessary logic to avoid screen blanking. Finally, both at niri startup and when switching TTYs, your screen won't flicker, as long as resolution/refresh rate stay the same.
Even when the screen does blank, it'll go faster, as there's now just one modeset instead of two (clear then draw frame).
#niri
Ivan MolodetskikhTook some fighting but I think I've managed to teach the new Alt-Tab to speak to the screen reader
#niri
Ivan MolodetskikhI finished and merged the horizontal drag interaction tweak from a previous post. It's very handy but can also be annoying when you want to move windows across monitors, so on mouse I restricted it to headerbar dragging (so, not Mod+LMB and not in the overview).
On touch however, it works for both headerbar dragging, and for Mod+Touch, so you can now easily scroll the view around.
I also added the thing where you can touch with another finger to switch between floating and tiling.

Ivan MolodetskikhDankMaterialShell folks set up builds for Debian, Ubuntu and OpenSUSE, so now it's super easy to try niri & DMS on those systems.
I added Ubuntu commands to the niri quick start guide: https://yalter.github.io/niri/Getting-Started.html
Debian and OpenSUSE here: https://build.opensuse.org/project/show/home:AvengeMedia:danklinux

Ivan MolodetskikhToday I'm releasing niri v25.11 with long-awaited config includes, Alt-Tab, true maximize, custom modes, and a bunch of other improvements! 
Enjoy the release notes :)

Ivan Molodetskikhfunny how while working on alt-tab i discovered that mouse scrolling on top of the DMS bar switches workspaces, which completely replaced any need i had for alt-tab, so i ended up never using it
this DMS bar scrolling feature also removed one of my main usecases for the overview
and then the new horizontal window drag gesture removed my other main usecase for the overview, so now i'm opening the overview quite rarely too
(both have their uses; just curious to watch my own habits shift)
#niri
Ivan MolodetskikhI've had one of those sessions today where I worked with a ton of random windows on a long workspace, while preparing slides for a uni scientific presentation. All kinds of various PDFs, file managers, InkScape, GIMP and so on.
Horizontal mouse headerbar drag to scroll the view was a lifesaver. Definitely a good choice adding this. Along with scrolling the view on DnD near the screen edge. Going through the overview, or always through the keyboard, would be very annoying.
#niri
Ivan Molodetskikhyuxqiu just improved the default GPU detection logic in Smithay, so niri-git now works out of the box on Asahi and Pinephone devices, without having to manually configure render-drm-device!
#niri
Ivan Molodetskikhi added the pointer warping thing from blender to when you drag the view around in niri with the mouse
hf with this new way to pass time during boring meetings
(on a more serious note this helps when you need to scroll further than the edge of your monitor allows)
also unrelated: merged optional config includes earlier today
#niri
Ivan Molodetskikhon niri-git, the nautilus rename popup now works properly with IMEs running
(and generally popups with text fields should work now)
#niri
Ivan MolodetskikhExperimenting with a restructure of the niri rendering code to uncurse it somewhat by getting rid of all complex impl Iterator chains and lifetimes, which also lets me remove some intermediate small Vecs. In essence, going from pull to push iteration.
I'm surprised that the result is consistently 2-3x faster than before. Wonder if it's the Vecs, or if inverting (massive) codegen'd iterators into a normal call stack passing a closure arg, providing the main benefit
#niri
Ivan MolodetskikhFinished the push-based rendering refactor, made a write-up here for the curious: https://github.com/YaLTeR/niri/pull/3113
It even ended up with a negative delta (+762 -780) which is always a W.
Btw I ran the comparison on my Eee PC and there the difference is even more extreme, like 8x faster rendering list construction (which is once again only a part of the total rendering time, and notably doesn't include actual rendering, but still nice).
