@Heel: For the first question: LED implements a complete C-Parser, therefore it's just bad luck, that in this screenshot no user-defined functions are listed.
As i want to finish LED pretty soon (less than 2 months), I won't be able to implement all of you wished features.

- Bookmarks: Planed and will be implemented
- User definable execution keys: what do you mean by that?
- Position Remembring across files: bookmarks?
- File comparison: Not planed at the moment

ATM I'm working on finishing the searching system (especially fast regex searching) and finalize the Auto-Intend feature.
