I think Python (x,y) should consider replacing SciTE with a Scintilla derivative instead. Geany is in active development, and is in the same family as SciTE, but seems more user friendly and easily extensible. SciTE on its own is nice and light, but customization is annoying and frustrating at times. In particular, syntax highlighting rarely/never inherits from the common style settings, but is individually hard coded for almost every language supported.
