HUGTOM  Just what I was after- a neat drawing window that allows me to handwrite, annotate images and trace over bits of the screen. Smooth and responsive using a Wacom tablet. The 'tracing paper' option (look for the little slider in the top right of the window) that allows you to trace over the screen without picking up the background is genius- it fits my illustration workflow perfectly. Thanks!

GCOGHILL  Nice little sketching/doodling application. Works fine with the Wacom, and in contrast to the previous review I found everything to display smoothly.

Nice basic options for the canvas: plain, transparent, lined paper and grid.

One thing that would really make this killer: in the transparent canvas mode, there should be an option to capture the screen area behind the window (including any marks if you started to draw before capturing the screen).

The Crop/Resize to window dimensions feature is nice, but it bottoms out at approximately 250x250 pixels, can't go smaller than that. This app is more for sketching than image resizing, I am just seeing how far I can take things.

This app is bare bones in it's simplicity, but it seems that is exactly the developer's intention.

It would be nice to see the brush size as the cursor. And I am almost thinking that this app might benefit from the HUD style display.

Saved JPG files are decently sized - Photoshop JPG from "Save As…": 40K; PS "Save for Web": 6K, CocoPad JPG: 12K.

MAC MAIL  It's not a bad idea, but it needs to refine a lot in preferences to be able to control (smoothness) all the roughness when writing. It's so difficult to write nicely (handwriting looks like little kids writing).

I won't use it until it's fixed.

That's my 2 cents.
