Shortcuts in the Toolbar
Shortcut icons (like bookmarks) to take you to measure numbers or rehearsal markers. You could give it a name, maybe limited to 10 to 12 characters and be in the tool bars. It would have options such as to align left, center, or right the top stave. Also an option to immediately start playback.

The Timeline function gives you a more graphical way to navigate at the expense of screen space. See https://musescore.org/en/handbook/4/timeline
