Include 'Podcast' as a genre option
The Genre page would be perfect for listing podcasts. I download my podcasts using a PC and sync them to /sdcard/Podcasts. I can play them with the file browser, but having a list of the current files would be so much easier.
That feature already exists ... I personally use the BeyondPod app for podcasts and have chosen NOT to share/include podcasts with my other media, but if I enable this option in BeyondPod, they all automatically show up in Meridian under the "Podcast" genre. If you're not using a separate app for podcasts but rather copy them from the computer, just make sure you tag the genre appropriately in your media player before you copy them to your phone, and you should have no problem.
