Thanks for a great app.
Could you use QColorDialog for the Color picker ?

I think I could add it as an advanced option to choose a color. I like the actual color picker as it's elegant an compact but I understand other people could want to have extra options.
I will have to redesign the menus when I add some extra things to the config window.
@lupoDharkael I think we can combine pin capture on the dektop and color picker.
After taking the color, the color info will be attached to the desktop, like this


Add color picker for drawing tools
Take a look at joxi.net
Or in the short term, can you let users customize the colors e.g. in the config file ?
[ColorPicker]
color1=#123456
color2=#987654
...
There is actually a color picker now. If you hit spacebar after starting a screenshot it will bring up a new window with a color picker.
