Ok, now I fixed the button labels (they're shown only in landscape mode, so more space for portrait mode), there is a setting for backlog size (default 15k, previously 7k), tried to remove even more of the missing letters when typing while channel activity, keepalive setting is actually saved. Maybe something more, dunno. Also updated some translations.
Test it and shout if it doesn't work. Hopefully this'll be working well and we'll get 0.5 out :)
And I noticed that my version control wasn't working due to network problem so I uploaded a wrong version. So I'll update this as 0.4.98b, please make sure you have that version when downloading (it says 0.4.98b only after you start it).
And 0.4.98c released, fixes colors in topics.
