Otto,
We are happy that you enjoy it, but are you able to automatically manage multiple PRG files and C files also, all in the same project ?
Actually we see VSX as a very good resources editor, but not as a project manager yet (until it is developed and implemented). Also syntax highlighting, intelliSense, source code completion, etc. has to be developed for PRG files (so we also get a good source code editor).
Those features can be implemented, as VSX is ready for them, but we need some time and work to develop them
In the meantime, UEStudio is a superb project manager and source code editor, though it lacks for a good resources editor (but we can use VSX for that)
