Might just be me, but I don't like double tap to skip. Findroid has another scrubbing method I've not seen anywhere else but I wish it were the standard.

When you drag your finger to the right, it says how far you're about to skip ahead. The longer your swipe, the further you go. When you release, it scrubs to that timestamp. Same with going backwards.

I find it faster, more accurate, and more versatile. The only thing I don't like about the Findroid player is the UI timeout is twice as long as I need it to be.
