Bit and Eraser

I would like to see the addition of bowl bits to the tool box and the parameters preloaded into the software. So many people use those bits for bowls, juice grooves, etc. Also, remember drawing on “paint” as a kid on the computer? I think it would be extremely nice to have the “eraser” function added to the software as well. I know I can highlight the work and set the cut depth to zero or realign the borders manually. However, i am finding a lot of SVG files that are more suited for detail work or for lasers. The majoirty of the files are great but it would be nice to be able to delete the areas i dont want and then if need be i could copy,flip, and realign things to create more options and projects that i could do and make.
