Hi pubpub-zz,

I really appreciate your contribution. I think that the tools you added (free-ink, line, square etc.) working as a second parameter to the pen attributes (color, width) is a very interesting idea. But as i may have expressed before, I hope to keep this software simple, even though I regret it could not provide line/arrow/square tools that many ask for. Adding these tools will cause significant change in the base structure of the code as well as user interaction interface design, and this will not only induce too much future effort to maintain the stability of this software, but also defy the aim of simplicity of this software.

I tried your build and it seems to be too buggy. For example, sometimes the line jumps out of screen when I releases mouse button; the pan tool and the mouse pointer tool is totally broken; and when I click the eraser tool the software crashes. I think that this could be a proof that adding these tools is a very difficult work. Even if you are able to fix them all, still the trade-off between the tools added and the user interface complication added may not be worth it in my view.
