[FEATURE] Save Layout button

[JustJoostNL]

Is your feature request related to a problem? Please describe.
No, it is not related to a problem.

Describe the solution you'd like
I want that I can open all my windows, like 3 driver cams and a mainfeed, then click a button, like save layout and that saves the layout all the windows are in, this make things a lot easier and quicker i think, the config file 'multicommand/layoutcreator is also a feature i think that should not be removed, so the save layout button is a extra on top of the config file 'multicommand creator'

Describe alternatives you've considered
A alternative is using race control (a other f1 tv viewer app) or using to config file, but in the config file it is much harder to make layouts, a save button is just easier and quicker.

Additional context
You can check the racecontrol github here for information about how they implemented this feature in the software.
Also if you save a layout it will popup in the config file, as multicommand/live session hook and then you can change it there still after you saved it and add extra mpv/vlc parameters if needed.
