Resize panes like in Vim/Sway tiling window manager (even sizes, relative to current pane)

[enoryw]

The size of panes when they get created and resizing panes after never seemed natural to me--is it possible to make them similar to Vim and Sway tiling window manager? I haven't done extensive testing, spent a few minutes to determine the following:

• In Vim/Sway, when panes are created, all panes are resized equally. Sway does it smartly--it resizes only panes in the direction of where the split was opened, whereas Vim makes all the panes "equal size". I prefer the behavior of Sway--in Tmux, not all panes are resized and when it pane is created, it only splits evenly within the area of the focused pane before the pane was created (Sway does this too, but only with its explicit split h/split v--it defaults to evenly resizing panes in the direction of the split which I prefer.

• Both Sway and Vim resize panes (they call them windows) relative to the focused pane, so regardless of where a pane is, the same binding minimizes e.g. the width of the pane. Tmux doesn't seem to have such binding--resize-pane is based on top/left/down/right. Is it possible to get Sway/Vim's behavior (i.e. "make width/height larger") as opposed to Tmux's resize "to the left/right/up/down"? The most important factor for me is to have them all consistent in behavior to reduce cognitive load.

P.S. Unrelated, but does anyone have workflows to aid in focusing sessions when using a tiling window manager? I find that I often switch to the workspace with Tmux in it, then switch to a session I'm in and then sometimes to the window I'm looking for. I could have a session for each workspace, but I'm also thinking perhaps a dmenu-based script which somehow lets you fuzzy-search for windows in all sessions and selecting it will jump to the workspace containing the tmux session, then focus on the intended window.

I don't think we're going to change resize behaviour. You can use the after-split-window hook or change your split-window key bindings to arrange the panes evenly after you create a new pane.
