remote set-background-opacity affects only one window of the instance

[sergei-dyshel]

I'm running kitty with multiple main windows in one instance and listening on UNIX socket (--single-instance --listen-on unix:/tmp/mykitty) and trying to control it remotely (@ --to unix:/tmp/mykitty) from outside. I noticed the following inconsistency when running remote commands: set-font-size changes font in ALL windows but set-background-opacity only affects one window (I guess the first one opened).

When sending remote command from inside one of the windows, set-font-size affects ALL windows and set-background-opacity affects only current window.

That's because you cannot set font size independently in kitty windows.
You can in top-level OS windows, but not in windows inside a top level
window. And even that ability is relatively new, it wwas added after that
command was created.

I could add an option to that command to have it apply only to
the active top-level window and all it's sub-windows.

Thank's for quick response 😄
Now set-font-size and set-background-opacity behave consistently.
