It's up to you!

if you know that you create the same thing every time similar in your design (button, slider, structure ...) change the way you look on your design and find other ways to build your interfaces. Design has it's own characteristics. I never would say that there is a "peak", that's too simple for my opinion. Example

3.5.1 is released ! .. to fix the illustrator problem

Ohhhhhhh yes! It feels like every time I zoom in and out that this happens

I think it helps you to get better in thinking about design elements (buttons,sliders and so on), how they can fit perfect together and what you can do better next time.

It helps you to get faster results when you design a UI because after that challenge you've made so many different things that you surely learn from it.

AWESOME! Pixelmator is just "WOW"(when you're looking for a low price designtool) but this one blows really my mind. I will give it a try :)

Looks awesome!
