extra window that allows easy navigation across the workstation (Like Carla's)

Nobody has claimed this yet.

### Enhancement Summary

Carla has this overview minimap box that allows you to navigate the entire Patchbay, which can be useful for lmms

here's why, and what i believe is wrong with LMMS' current workflow:

1. Lets say you want to open the piano roll editor, but for some reason, it is all the way somewhere god knows, and you're trying to find it, but the problem is you dont know if the Ui for it is actually shown, or if you're searching for UI that isnt even there because you clicked on the Piano Roll editor too many times and now it's hidden. then you have to click the piano roll editor, search for it for another good amount of time, and realise that NOW you've made it hidden

or perhaps you're searching for a small effect, which doesnt have the benefit of Piano Roll's size nor has it's own little button. Painful isnt it?

2. You're always zoomed into some Ui's Ass, and it becomes hard to click the X button for that Ui if it becomes too big enough (i.e. Track editor, Piano roll, Project Notes), and so now you have to precisely AVOID clicking on the giant UI to move around which becomes tedious over time.

the overview box fixes all this by letting the user navigate the massive chaos and mess that is their project that they've spent hours on

### Implementation Details / Mockup

Like Carla's overview minimap box

if you managed to bury it inside another piece of ui to the point where you have to move THAT ui, congratulations, you failed, and have defeated the whole purpose of this feature

there needs to be a way that it's always visible to the user without it being a nuisance itself

### Please search the issue tracker for existing feature requests before submitting your own.

- [x] I have searched all existing issues and confirmed that this is not a duplicate.

No files or tests are mentioned. Start by studying Carla’s overview minimap behavior and how LMMS currently exposes and positions editors such as the Piano Roll, Track Editor, and Project Notes. Done means a persistent, non-intrusive overview lets users locate and navigate open interfaces across the workstation.
