Lets make it the best one

I love this app. So far after working with many different apps this is my favorite. But it can be improved. For instance it will be awesome to have an eye dropper so you can easily pick colors from the picture, or keep using the very same color just by clicking on top with the eye dropper as in Photoshop. I also will love to have a water color mixing kind of tool, to blend colors, same as Sketches 2 has it.
And my last comment I dont know if it is because of my stylus (Wacom Creative stylus 2) but I dont get the difference between the brushes, if you set the same opacity, size and brush type, the five tools on the side, do exactly the same, so maybe some instructions to understand what is the difference, I had been Googling it to find out the difference between the 5 tools but not explanation yet. Thanks for such a great free app.
