First of all, I want to say to the developers of Geany that this is a very impressive piece of software! I am amazed that I have not discovered it until recently, because it is really too good to have such (relatively) little exposure.
The problem I'm having is this: I'm not getting automatic indentation for Python files (it seems to be working as described for C++). I have searched the SF bug tracker, changelog, and this mailing list, and found no mention of this problem.
In fact, all I found was great stuff about how Python indentation was being improved (to recognize comments after a colon, for example), which I was looking forward to seeing in action.
I am using Geany 0.13 on Windows XP Home. My autoindent mode is "Current chars" and is on, and the status bar shows that the file is indeed recognized as Python.
