@herrgnatz One correction: the latest AndStatus version is 31.02 (available at https://play.google.com/store/apps/details?id=org.andstatus.app). It has some improvements of the Conversation view, see http://andstatus.org/changelog.html
Unfortunately, it looks like I didn't inform f-droid on this release, will fix this next week, when I return from vacations.
Currently greetings from Flores island, Indonesia. https://loadaverage.org/attachment/3382023
