I think this gets brought up pretty regularly, but the issues is that the drawings are vector graphics. It is far, far more difficult to try to "erase" part of a vector drawing than a raster one. Considering how even professional vector programs (like illustrator) seem to even struggle a bit with this issue, I think it's pretty unlikely that you'll get an eraser any time soon (though, hey, anything could happen!). Kristin C. (one of the mods) explained it in this thread: <a href="https://app.roll20.net/forum/post/3239/erasers#post-26705" rel="nofollow">https://app.roll20.net/forum/post/3239/erasers#post-26705</a> "When you're drawing on the tabletop, you are creating a vector-based drawing. Each vector line/shape is a series of mathematical expressions that tells the application how the object is to appear on your screen. This is why your line remains crisp if you increase the scale of your drawing. An eraser tool that you would normally find in MSPaint/Gimp/Photoshop is used for raster-based images, not vector. A raster image like a BMP, JPG, PNG, etc is comprised of a large mass of pixels. An eraser tool is used on raster images to remove said pixels."
