Just spend a good amount of time creating a bunch of manual support for a 3d Hubs order, since Simplify has a bug not supporting floating features, and these models have a ton of them:

Then I accidentally hit "clear manual supports button" because my mouse is twitchy. Anger. Then I accidentally selected another model on the platform without realizing it, and accidentally hit the "apply based on overhang", which mangled all the custom supports I'd already added to it. Rage building.
So maybe I shouldn't beer and print, and maybe I need to use a muscle relaxant on my mouse finger. But considering any modern 3d application has undo (Maya, Max, Blender, Fusion 360, 123D Design, Meshmixer), and even other free slicers (ReplicatorG, Makerware...), it kills me I'm paying for software with no undo. When I used Alias Poweranimator in the mid-90's it has one
level of undo. That's all I'm asking for.
Please S3d, please implement undo. Your dumb users need it.
