Every so often, I mis-click, or the map glitches up whilst I'm placing various objects on, causing a whole bunch of 'em to plop on to the map, and then I have to go through the arduous task of deleting every single instance of whatever it is I plopped down! Sure, I could just do the "delete all", like, if I put down a bunch of objs, I could put delete topmost obj, but If I'm not on the obj thingy, or if the objects aren't on the top layer, I'd like to be able to delete all those instances of that one object without going through every single space on the map one's in. What I'm suggesting, is that when you're using 'select' on the mapper, and you choose a certain object, that there could be an option to "Delete" all instances of that object in the highlighted space. It's nothing too big, but it would be really convenient!
