I had a suggestion where the zelda quest editor was revamped to use expandable lists to organize various flags, properties and arguments.
for example the combo type editor could benefit from something like this.
where one tab contains a list of scripted meta types and another tab contains a list of all the enabled metatype properties
enemy and item editors could use these as well to organize flags and things onto a single tab instead of having multiple tabs per 16 flags
the expandable part would just be there so users can expand slots in the list for example the enemy selector it could start with 256 entries but more could be added in case of large modules
