I don't know if I'll be keeping the extension and for how long, but for the moment I'm still motivated and working on it. As I said, I'm working on a new version with some minor fixes, some extra tooltips and more customizations on the skin/theme.
Regarding the Distinctive Features, yes, that's something I'd like to add in a near future but I reckon that for the moment it's not a big pain in the arse to fill it manually since it means typing 2-3 words.
Thank you!
