According to rumors floating around the web today, RIM is working on an enhanced Gmail plugin for the BlackBerry. Most BlackBerry and Gmail users are already frustrated because several Gmail features do not work on the BlackBerry. Read/unread status doesn't always work, and labels don't always show up. It looks like RIM is trying to address some of these issues with the plugin.

New features include:

See your Gmail based emails in Conversation View for simple topic management

Add and remove labels and stars to emails to keep inbox organized

Archive and report as spam actions for mailbox management on the go

Search your entire Gmail inbox

The plugin is in beta right now and only insiders have access. Stay tuned.
