A button to collapse without disabling it

[Raoul0201]

I would like to get a button so you can show und unshow the addon without disabling it, because currently its often overlapping with other windows and it would be a quick and easy fix.
I also would like to get a setting to lock it attached to my dungeonfinder window because currently as soon as you accidently deattach it, and it happens a lot because it only requires 1 click, it does not move with my m+ window.

I will think about how to allow to close the window permanently.

There is already an option to lock the window next to the dungeon finder, think it's actually the first one.
