As I was working on the Kumihimo generater I was struck by the idea of some features that would be very helpful; they are as follows:
Undo- It is so easy to click on the wrong pixel, it would be nice to be able to fix that without having to completely redo the pattern especially if the mistake is at the end of the design.
Color Match- Being able to click on a color already in the design and work with that color again. With the color spectrum so vast it is difficult to match a color if you want to add more of it, and you don't always think to write down the codes for the colors you are using.
Finally,
The Wheel- Being able to change the color on the wheel itself rather than on the sample would be great.
Thanks for considering any or all of these suggestions and I am sorry if you have already heard these suggestions are they are unpractical to implement.

I can't tell you how many times I have had to start over just because there is no undo button :-(
