Yo, I'm late to replying, but thanks so much for that purchase - I really appreciate it
While the software isn't true open-source at the moment (since the source is available, but it's not open-source licensed), I'd like to review the license at some point and open it up to people...
Thanks for the suggestion - that's been added in the next big update for v0.8.0. A beta of that will be coming shortly!
