Line tool for seem painting

While it’s nice to paint on a seem I would love to paint in straight vertical lines.

I have tried to paint on seems to move them and they are all jaggered.

Please add a line tool.

It’s called a Seam, not Seem. But I fully agree that a line tool would be great. I often tried to place the seam on a vertical line and doing this with a mouse and the circle tool is a pain

Hey there, sorry if I’m in the wrong thread, very new. But It would be awesome if we could get a square (like the circle now) and a cube (like the sphere now) in the paint menu. Also I was thinking of a “push shift type button” and it would make a straight line with said option or something awesome like that? Maybe some one knows where this post should be at?
