Hamster is important for may daily workflow, as I'm using it for time accounting. While hamster-time-tracker-2.2.2 itself, as shipped on Tumbleweed, depends on python3 only, the build process requires python2. It's therefore in danger to be kicked out of the TW repos. Updating to 3.x will likely require some homework.

Edit after hackweek 19: Almost done. Hamster 3.0-beta is available from the "Office" project on OBS. This took more efforts than foreseen though, because I got involved in beta testing and ended up testing, fixing issues, and going through tedious discussions with the current lead developer.
