Excellent! Thanks both of you for testing.
As for the keyboard and spacing, I am not a very good programmer, but unfortunately, anchoring the message field to the keyboard did not work properly, perhaps because it was written in QT creator for use on KDE environments, I added lomiri components and the code I saw in other apps for anchoring, but it doesn't follow the standard rules for anchoring to the keyboard like I have seen in other apps (by my trying their code in the Kaidan app). For better or worse, I went with the "wasted space" because I think on smaller screen phones this wasted space is less, and I wanted to make sure that it was not covered by the keyboard when it was displayed.
But, I'd happily accept any input if someone could try some other keyboard code that would work.
As for landscape mode, you are right, it does scroll the list of contacts, but springs back making it hard to choose contacts that are at the bottom of the list. I'll look at that for sure.
For all looking to send messages with pictures or files (audio files are good too), you can send any file if your server/account supports it. For instance, jabber.sdf.org does not support sending files, but ubuntu-jabber.net and conversations.im both do, and the icon to open folder/document doesn't appear in the compose message bar unless you have an account/server that supports it.
Ah, yes, the search field is wayyyyy to small!
Thanks for some great feedback! I'll take a look at this, perhaps early next week.
