Uploaded image editing

It would be handy to be able to edit an image that you import to use. Examples could be the ability to recolour (similar to publisher) or to be able to manipulate the image with a fill colour in the image (similar to paint functions) I know you can do some things with drawing tools included but not quite a complete set of options spray can is very slow, unable to draw a line or can't create a point to point to point line for custom straight shapes unless I've missed something*Can't draw a line then manipulate a curve in it. obviously could do in another tool then import into plasfy but would be great to have a one stop shop. Many thanks
