It looks interesting. But unfortunately it's still just an editor when it comes to AutoLisp, not an IDE. Sure the tools are quite advanced, but what's needed to get past being just another NotePad++ is a REPL which reads the ACad environment.
I.e. it needs to also replace VLIDE (with its Lisp Console and Trace Windows, and its captips should then be able to read symbols in the ACad environment). Either by becoming a built-in editor inside ACad (as VLIDE is), or link to the ACad environment from outside (perhaps ActiveX or preferably DotNet).
BTW, is this editor also based on the Scintilla libraries? Every other editor I've yet seen is, including NotePad++, SciTe, TextPad, UltraEdit, PSPad, etc.
If it can't integrate into ACad, then I'd rather see something like
Light Table or
Sublime. But that might just be me.
Still, a thumbs-up to the developer - great work!
