This application still has one of the best interfaces I've used (other than MacTube) that is uncluttered. The current beta uses the new Google-imposed format too.
I look forward to tweaks for keyshortcuts and more control over sorting the search results, i.e., by date, by text string, etc., which is really important when looking for video on Youtube.
I would be willing to contribute some $ towards this application as well, especially if I don't have to go through AppStore to get this.
