It's not much that I don't do bug-hunts, and more that I only check this forum once a week or once every 2 weeks, mostly at weekends, and sometimes I end knowing that there is a newer version after the bug-hunt version.
About bug-hunt, I review the code when adding it to the gallery and end up correcting all bugs I find even if MITY didn't correct it, just to make sure the gallery will be running as intended (although I don't review the dialogs, that may change between versions).
About working on the next version, it's Saturday late night here and I don't intent to do it right now, I will probably release a new version tomorrow.
