Alias default menu items

[FelixKratz]

I think it would be super cool if we could alias default menubar items in sketchybar. I have some menubar apps that I really like (specifically: meetingbar) and that are complicated to replace with shell scripting.
I would thus like to have the ability to snag, e.g. meetingbar, from the default menubar into sketchybar. I know this is possible, because bartender has something like this.

What I think is needed:

• Get the window of a menubar item, most likely through something like

CGError SLSGetProcessMenuBarWindowList(... dont know signature yet ...)

• Unregister the menu item window from the default bar via something like

CGError SLSUnregisterWindowWithSystemStatusBar(CGSConnectionID cid, CGWindowID wid);

• Move the window into the correct sketchybar bounds and order it on top

I am not exactly sure how Bartender is doing this, but it requests screen capture access, which leads me to believe that they might be recording the
bar item window and then place the capture inside of their bar.

Maybe someone has an idea on how to do it properly, or knows someone who could have an idea?
Could also be that such a feature would be a bit too sketchy, though...

I have checked the binary of Bartender, and they indeed seem to do it via the above mentioned SkyLight call:

Very crude first implementation which will segfault at every opportunity it gets, when not doing very specific setup tasks 86da5be. Will polish this some time soon.

As of 2012375 this is pretty nice to use. Click actions still missing, I dont need them however.
