Feature: UX Item Menu Interface Separators

Thanks for this wonderful program. I tried searching for what I was looking for before requesting this. I realize this program is a work in progress and just hoping there is an option.

**Is your feature request related to a problem? Please describe.**
My Item menu in the program is very long due to the plugins I have. I am having trouble editing it and making it easier for my visual needs. I am dyslexic and struggle with blocks of text.

**Describe the solution you'd like**
Instructions on how to edit the main interface's Item menu, and add separators if this is not available.

**Describe alternatives you've considered**
Looked on site, tried looking through menus.

**Additional context**
