Nice job!. I have been looking for a good alternative to notepad++ for some time and this seems to be it.
There are some features that imho would be nice to add:
- Custom compile flags
- Shortcut keys - Like [F7] to compile
- A button for starting frontend
- An option for disabling sound and all the other stuff when running
- An "update IDE" option from within the IDE
Have you thought about open sourcing it? I for one would love to help out with the development
