What would you like dabr to do? If u want to know whether there is new replies,u have to click "replies" to check it.so it would be nice if dabr add this feature

And I think API status is also a useful info

How would you prefer dabr to do it? put it in top menu or somewhere easy to find

btw,yyada(https://code.google.com/p/yyada/) support these features

Dabr doesn't store information about you, so it's not possible to know what the last DM or Mention was and this isn't kept with an API call from Twitter. Also to see if there were new mentions or directs, Dabr would have to make regular API calls to check if there was anything new, adding overhead and reducing available API requests for other calls.
