So, I saw that there was no Eraser, so I clicked on the Pen and used Transparent but it still wouldn't erase. I needed the Vector paint thing because I can move the shape I am trying to edit into a Head, I made an uneven line and thats when I noticed....no erase at all, not even transparent Pen? Also another thing I noticed....I tried using the Bucket tool to fix a few colors in Vector, but it wouldn't work. Yet the Eraser and Bucket tool works in Bitmap...
It's a missing feature. We know both costume editors need work.
I have managed a work around, I will use the Vector to move shapes and create a base drawing, and switch to Bit-map for the major details.
