I wanted a commandline IMAP mailbox checker so I wrote one: imapchkr

Normal output for this is as below:

➜  ~  [jamespo: 0/190] [gmail: 0/80] 

But I decided I wanted to embed it in my GNU screen hardstatus so expanded it to offer a short output option (imapchkr -s). See bottom left corner for output.

Configure your ~/.screenrc like this:

backtick 1 60 60 /home/james/bin/screen_agenda
backtick 2 90 90 /home/james/bin/imapchkr -s
hardstatus on
hardstatus alwayslastline
hardstatus string '%{wk}%2`%{yk}%1` %{= kG}%-Lw%{= kW}%50>  %n%f* %t%{= kG}%+Lw%<'

screen -t root
screen -t mail
screen -t root

I'm also using gcalci for Google Calendar appointments.
