In the image below you can see that I have a .git folder that appears since I created a Git repository for this project. I'd like to be able to hide it in Ebase since I would never want to go in that folder via Ebase.

Proposed solution: when right-clicking an entity/folder in the tree, add an option to "hide" or "exclude". Add a button at the top of the Entities windows (where quick search is) to show/hide excluded folders/entities in case we want to re-include a folder/entity that we had previously excluded.
Alternatively, since the .git folder is hidden in the Windows file system, maybe simply not show in the Entities window folders/entities that are hidden in the Windows file system?
