[Feature request] Maximum window width when only a single window is tiled

[Alanazane]

It can be useful to have a maximum window width in situations where there is only one window tiled. This is mostly useful for those of us with very large or ultra-wide monitors, so the window is centered rather than spanning the entire screen (which can be quite awkward).

This implemented in Sway as smart_gaps inverse_outer With Sway you actually set the gaps to the side of the window but the result is the same.

Side note: Sorry if it isn't quite time yet for feature requests :) I'm really looking forward to Cosmic, with the native tiling it'll likely finally move me from Sway. :tada:

Ping @pop-os/ux. Sounds like a good idea in principle, but I am struggling to imagine how to communicate this setting effectively in settings. Though this targets people mostly using tiling setups, so power-users, so maybe this might be good enough as a hidden config file option?

[Alanazane]

I think having a hidden config file option would be totally adequate! Particularly since this is something I imagine most of us will set up once to turn it on, and never touch again.

Hidden option in the config file sounds good to me, at least for now.

but I am struggling to imagine how to communicate this setting effectively in settings.

Each tiling option should have it's own settings. This setting should fall under center/master layout, be it configurable through a file or the gui.

This is a feature we really need with a widescreen monitor. I have implemented a proof of concept to see how this may work, and found that it works nicely for me. I have implemented limiting the width to 50% and centering the window.

For those wanting to test: https://github.com/griccardos/cosmic-comp

I have not implemented the config setting, but can give that a go if there is any interest.

[rwjack]

@griccardos cool, so how do we test this out?

[griccardos]

@rwjack make sure you have rust installed, then do something like:

git clone https://github.com/griccardos/cosmic-comp
cd cosmic-comp
cargo build --release
sudo cp target/release/cosmic-comp /usr/bin/
