How could I set default size for floating window?

See title.

Unfortunately there's no way to do this yet before opening the window. After opening the floating pane you can resize it as you would a normal pane (eg. with alt +/-).

@imsnif I think should be easy to solve, are there any difficulty?

The difficulty with such issues is usually not technical, but rather about working hands.

I set the default size for a floating window through the layout:

layout {
    pane {
        pane
    }
    floating_panes {
        pane {
            x "10%"
            width "81%"
            height "50%"
        }
    }
}

Now I can open a floating window with the customized size even though have closed it. But the downside is that each Zellij session will start with a floating window for the first time.

If you do this with the default swap layout instead, it won't be opened on every session and you'll get the same effect.
