1. Group-Shared Recipes: There should probably only stand recipes of your group.

2. If you dl a recipe of another group, the error "Error: Cannot find the specified recipe" comes. That isn't helpful at all for the player. A "wrong group" is appropriate. (Of course, with 1 this isn't necessary)

3. Had a crash the first time I tried "wiggle/shake or shake/wiggle" http://fold.it/portal/recipe/1741 Didn't occur again.

4. Recipe uploader should be able to tag recipes

5. special search in tags and/or recommendations
