I have a few more feature requests if you don't mind
Replace all function - replace all execute script 4 in cloud no1 to script 4 in tifa no2
Wrap text in speech marks button - highlighted text gets wrapped in speech marks
More specific copy and paste - copy lighting and individual scripts, as well as drag them to rearrange them.
View walkmesh, entities and arrows over the actual background. That would make placing objects easier.
Sorry if that's a lot, these are things i've been thinking about for a while
