A wicked priority theme for the BlackBerry Tour from SocksInsideOut which is totally free.
The priority is nicely laid out and as you can see for yourself from the picture, the usage of the tabs in the theme is really a great addition as well.
A number of other themes have used this feature before but not to the same extent as have been use in the priority. The theme is just in testing stage at the moment but be sure to come back and check out the thread in the forums and post any bugs or feedback to enable the developer to have them corrected.
