So, I just installed this. Nice to have a native client, but a few caveats:

1) Is it possible to archive conversations/chats? (eg. remove from the active conversation list without deleting them completely)

2)Any line breaks (enter) i put into my messages are not transmitted for some reason. Is this a bug, or a "feature?"
(Edit: Ok, noticed this only happens when I try to circumvent the below issue and have "send on enter" turned on. If it's off and you send by pressing the send button, line breaks are included in the message, as they should).

3)Likewise, if I have "send on enter" turned off, and write a really long message, the "send message" button gets scrolled past the top of the screen, and thus I can't send the message at all (without going into settings and turning on "send message on enter") due to the send button being off-screen on the GUI.

...And If I try to circumvent that problem & click on the message window to turn off the keyboard & be able to scroll the message list, the "send" button frustratingly changes into the microphone button...

And lastly, something less critical, It would be nice if there'd be an option to chose the size of inline-displayed image thumbnails (eg. small-medium-arge). Coming from the default android client, the current one feels a bit small in comparsion - you always have to separately open images in order to make out anything of them.
