Linux Mint: replacing gnome-screenshot

The default screenshot program on Mint doesn't really do it for me.

 

So I started investigating a better solution.

Lubuntu Keyboard Shortcuts

The one thing I hate about my lovely ASUS X401A laptop is the touch-pad.

Its just a plastic rectangle that clicks when you press along three of the sides.

I guess there are two problems with my touch-pad:-

1. Clicking the mouse tends to move the cursor, so I often select the wrong menu option or highlight the wrong text
2. When typing, the cursor sometimes moves, so text gets inserted in the wrong part of the document (maybe my hands get too close to the touch-pad)

Since the laptop boasts "...palm proof technology..." I suspect my problems are due to either the Linux touch-pad driver, or its configuration settings.
