I have used the editor a lot recently and I have some more feedback.
The find/replace dialog constantly annoys me. I should be able to press escape to close it rather than just ctrl+f. When opening the dialog, it should also select what was there previously so I can quickly change it.
The upload feature does not work if you have copy/delete selected because it doesn't know where to get the file since being deleted.
The "include" directory in the build configuration is misleading since it's apparently expected to actually be the directory which contains an "include" directory AND the spcomp.exe. It would be nice to have a separate option for specifying where the compiler is located, and the "include" directory should be the actual include directory.
Due to the limitations with the upload and command line features, I am finding I am simply doing it all myself from command line which defeats the purpose of having it all in the editor. As I said in an earlier post, adding more command line hooks such as Post-Copy and Post-Upload would be very useful. You seem to have the idea that too many boxes is a bad thing but more configuration options can only be good imo.
I just noticed you have already been working on adding built-in RCON support so thanks for listening to my feedback!
