Mouse gestures for Blender, pretty interesting. Thanks! I disagree that it's easy to set up though, it's a pain in the ass. Copy paste command, press add new at the bottom of the category, paste, change keys. Especially not easy when all of the categories close randomly when pressing the add new button. Well not randomly I guess, the search keyword gets cleared when you press the add new button and that messes up the menus somehow. There should just be a duplicate key button that copies the command and places it right below.
Now the question is, what else than viewport views could be useful commands with this method? For now I added rotate edge, subdivide and merge. It feels pretty good, merge is a bit awkward when you have to do it vertex by vertex though, it would probably feel better if you could select a bunch of edges to merge and some other edges to merge them to and merge them in order.
