Fair enough, and not good if that is the feedback about a well-supported plattform. Still looking for a more-than-basic desktop client.

That's interesting; what Android apps do you like the UI of, out of curiosity? Conversations basically follows the Android design guidelines to the letter, so I'm curious if it's all Android apps or just something about Conversations. The only problem I ever have with the UI is the unreadably small font size (but at least there's a setting for that).
