Startup sessions, splits and window sizing issues

[pm5k]

Hi, I am having trouble figuring out what is the standard (accepted) way to setup a startup session which contains properly sized window arrangements. I cannot find anything in the docs to show how would one achieve two distinct Kitty os windows side-by-side, but the first one is sized to take over 30% of the available screen space and the other - 70%, for example.

SO, what I have so far is this:

layout splits:axis=horizontal
launch --title=Neofetch --location=hsplit zsh -c "sleep 0.5; neofetch; zsh"
launch --title=Sys --location=hsplit btm
new_os_window
layout splits
launch --title=Projects --location=hsplit --cwd=~/Projects zsh
focus
launch --title=Generic --location=hsplit zsh

Which results in two os windows (from what I can tell, this is what you call them in the docs?), that share 50% of the space (each) on the desktop. I wish to make the first one only take up X%, while the remaining one should take the rest (but I do not mind specifying this manually).

Is this possible? I have resorted to this, because I frankly could not, for the life of me, figure out how to do the following in a single OS window using layouts (again, docs hint at splits being the right choice, but the way splits are auto-portioned made it impossible to achieve what I wanted):

+----------OS_Window----------+
|          |                  |
| neofetch |      zsh         |
|          |                  |
|          |------------------|
|          |                  |
|----------|      zsh         |
| btm      |                  |
+----------+------------------+

I tried making this layout using a combo of hsplit and vsplit and I just could not achieve it with any combo of hsplit/vsplit on the four launch instructions I had defined in the session file.

So I guess my question is two-fold.. Can the above ASCII table be expressed as a single os_window layout using splits? If so - how do I achieve that -- since I have not found a way to portion those splits in such a way that they respect that sort of layout in a single OS window. And if this is impossible -- how do I achieve a startup session with two os windows, one of which only takes up X% and the other takes up Y% horizontal space (whichever is easiest, I suppose, but I would prefer a single window with splits).

I'm a little reluctant to write this, but frankly I have spent way too long trying to figure this out on my own and would love some guidance as the docs were of no help here.

Thanks in advance.

There is no way to open splits at particular sizes using launch. However, what you can do instead is create the splits, then resize them using remote control, https://sw.kovidgoyal.net/kitty/remote-control.html Someday I might add a way to pass layout dependent options like biases for sizing to launch.
