Please provide any additional information below.
It would be nice to have a scroll bar on the right. It is impossible to see 
the older messages if you chose more than 10 lines to see (or for bigger 
screens 11-12 maybe). But 10 is too low and you need to see last 20 or 50 
tweets. In this case, the bottom of the window goes out of the screen and 
you are not able to make the window smaller and scroll down in order to see 
the other tweets, also to write a new one.
