Redo
By AGlass0fMilk
You know Undo! Meet Redo!
Well, a while ago, I was building and it occurred blatantly obvious to me that we have undo, why not redo? At that time, I didn't have the coding knowledge (or skill) to make such a mod. A couple days ago, I picked this one out of the dusty archives of my coding projects folder, and said "Let's have another go at this one." Over these past few days, I have been making this work with the things Undo does, and fixing the many bugs it has. And now it's done, so here it is! Redo!
Now onto the information about this command.
This command is sadly, not client-sided. And I have no intention of making it client-sided. In order to have the keybind for it (by default it gets bound to cntrl-y, but you can switch it in Options) you have to have the redo command as it comes with the client-sided file that give you the keybind. Otherwise, you can type '/redoBrick' to do it, but it's rather slow. It currently redoes bricks, Painting, ColorFx, ShapeFx (Undulo), and Prints (like Undo). I made the default limit of the back-history for Redo 500, but you can change it using the RTB server control (Requires server restart). I don't know what else there is to say. This is for those "oops" wand moments on floors (better for small builds =I) and when you undo something you didn't want to. It doesn't apply events, lights, emitters, or items back to the recreated brick, maybe in a later version. It doesn't redo entire builds at a time if you wand a baseplate with only one press of cntrl-y, as Truce said it should, but I hope this revolutionizes building.
Tell me of any bugs you find and I will probably fix them if they are major. Have fun!

No it's not camera magic, it actually works

And it works on Prints, ColorFx, Painting, and ShapeFx like I said above!
