Zgx, this is a really great app and probably the only one of its kind on the App Store; gladly paid the $1.99 to upgrade to get all the features.
With that said, here's a few suggestions that could make it even better. Some of these are taken from the ProTube app that's only available through Cydia so you may wanna check that one out. Anyway, here's my thoughts:
1. option to show downloads are taking place.
Perhaps a small red number could appear over the "download" button showing the number of downloads in progress. Currently, when pressing "download" on a video, there's no indication anything is happening. The download button should also be animated when pressed.
2. option to choose quality of download (360p or 720p etc.)
3. option to choose mp3 as the audio format
4. slight UI changes: remove the "mediaburner" title bar along the top with the "+" and "refresh" symbols. Perhaps place them at the bottom with the 3 other buttons. Currently the 3 at the bottom seem a bit larger than necessary.
