Definitely looking forward to widescreen support. That will be a welcome addition and to be honest I thought it would've happened by now. I've been waiting for a long time for it, still on 1.2 and haven't upgraded because I didn't see the point.
That being said, this front end is still super wicked. I have no intention of exploring anything else. I absolutely love the customization. Moreover, with the help of some here (Dark 13 and Kondorito) 16x9 is possible via a workaround. I just converted all my PBFX2 themes and they look great. Yes, it could use an update and I hope it happens soon. Still a great frontend though, no need for folks to be so upset. Honestly, what other front end comes close? I haven't seen one.
Sidenote: I still can't believe that people don't just choose one sound effect for their wheels. How can you guys listen to all the different sounds with every wheel click? That would drive me crazy Pick one and standardize on it. I chose the Guantlet 'gong' sound when you enter a credit and it's so much better. Get it together people.
