Description: The ttytter twitter client in the community repo gets a much more developed interface with the help of the perl readline driver developed by the developer of ttytter, called perl-term-readline-ttytter. E.g., you get command history, command autocompletion, colors (if the terminal supports ansi), autorefresh etc. You can read about it at http://www.floodgap.com/software/ttytter/#readline .
However, perl-term-readline-ttytter is still at an early stage of development, so perhaps you do not want to add it in community as a dependency. Also in this case, it would seem to me useful to insert it as an optional dependency. I have packaged it in the AUR in the meantime.
