Create own categories request feature

[AbramGh]

This is a request for a feature, so you can create your own category where you can put ports in that you use often and the board that you don't need to see doesn't need to be shown in your own category can be selected for the menu bar

Closed as resolved by #97 (custom process type overrides). Users can now right-click any port and change its process type, including Docker subprocesses. Overrides persist across restarts.
