☑ cool new feature
☑ could help many users!
☑ users can remove bugs on their on
☐ nice to have
☐ nobody needs it
 
What inspired this wish list request? 
Via 

a user can edit the main menu and [on windows systems] the toolbars.
 
Other menus cannot be edited.
Unfortunately, some of the implemented functions have bugs - and some functions are missing.
 
What is the improvement you would like to see? 
Please add the possibility to remove items from any right click /  red triangle / ...  menu and the possibility to add user defined items.
This will allow us to fix tiny issues which won't make it into a future version of JMP - or just in many years.
e.g.
- Allow us to perform more actions when right clicking on column name on  columns panel 
- Paste Column has a bug and should be replaced with a version without bug: JMP jumps 
 Is it possible to customize the Add Formula Column menu to include customize functions? 
  yes and no:
-  a user can not add  user-Defined mini GUIs , e.g. to add Modulo to the portfolio.
- Existing functions cannot be added to the menu by name.   (TS-00152405)
 
 
Why is this idea important? 
Less pressure on JMP developers to bugfix and fine-tune the GUI. Users don't have to wait for version N+2.
-> Users will be able to bugfix and tweak the GUI on their own.
