I ended up refactoring the magic glass and highlighting code quite a bit, I think there might be something worth checking out. As for other bug fixes, it would be great to have them in the patch tracker so we can sort them out. It would take me a massive amount of time to figure out what code changes are for what in pdl2ork since there isn't any version control (that I could find at least) and it seems to be a mix of 0.42 and 0.43 versions.
It's based off of 0.42.6 extended tree. As for submitting patches, I've been doing this in the past. Alas, a good number of them never got any attention which is not very encouraging.
Best wishes,
Ico
