I just created a Google+ Community. There I will post progress updates for the big 2.0 update.
You can also post feature requests and bug reports there. But please keep in mind that I’m almost completely rewriting the current app, so it will not make much sense to post minor bugs there as they will probably never be fixed for the old version. If there are major problems with the current version I will of course try to fix those.
Finally, I wish you and your families a Happy Holiday Season and all the best for the New Year.
