I'm a fairly new user, though I've been using Rainlendar for almost a year now. I really like the new 2.1 version. I use mainly skins others have created, though I tweak them extensively.
I would like to request an apply button on the options screen (and if possible the options sub screen), which would apply changes, but not close or change view of the options screens. It would really speed things up for tweaking values.
Double clicking to add/remove active skins from available skins, as opposed to needing to click on the arrows, would be a help as well.
Thanks for a great product, keep up the good work.
