I always thought that RIM could do better with their conference calling support. I use conference calling quite a bit on my 9700 and it is far from elegant. The view is quite frustrating to handle and seems like it was still built around trackwheel devices.
LouiV over at BBLeaks noticed that RIM has re-filed a patent for a new conference call interface that looks sweet. It makes great use of Avatars and lets you easily scroll through participants for more info about the call allowing you to split the call, chat, or email a specific participant. This could be really cool if RIM ever rolls it out.
What do you think of the mockup?
