Is your feature request related to a problem? Please describe.
The current categorization of triggers as either Event or Status trigger is not very useful for users. While that is a important internal concept and it's not something the user thinks about.

Also the combobox for the status trigger selection is getting too long.

Describe the solution you'd like
Slay Status/Event and use better categories
