Hi to everyone,
I'm new to the list and working on RoundCube.. but I changed him a little to satisfy my needs.
I implemented 3 features that you can check at:
http://www.vialink.com.br/webmail4/
email: msbrogli2@vialink.com.br
password: 123456

Essentially, it is:
* a checkbox at the left... to make the life of the ones who aren't familiarized with AJAX (in my case, my customers) easier...
  so, they can easily select more than a message..
* a droplist to move selected messages between the folders
* 2 buttons called SPAM and NO-SPAM.. they move the message to the folders Spam and No-Spam... but why?
  because I developed a script to periodically check that folders and train spamassassin to work better...

now I'm working on a preview window in the list page... like Outlook.. just click the message and see the content..
a double click maximize the message...

and my last modification (for now) will be a way to throw the compose page add emails from contact list..

sorry about my english... if i'm not clear, please ask!
