[Feature Request] Recorder UI enhancement in compact mode.

[fz0000]

Is your feature request related to a problem? Please describe.

I’m focusing on the content within the recording area and want to pause and resume recording at any time. It would be better if the record/pause button remained fixed in position, so I wouldn’t have to move my mouse.

Describe the solution you'd like
Use a fixed window layout.

Describe alternatives you've considered
Maybe we can make the window a bit wider?

Additional context
Maybe it's not really a bug since I'll probably just use keyboard shortcuts instead. But this UI adjustment may slightly improve the UX.
