Implement simple widget representing one-axis buttons (like triggers) in main window

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

Instead of using a regular button for representing triggers, it would be nice to add to it some kind of indicator showing current value of axis.

Maybe the background of a button could serve as a progress bar.
