A few feature suggestions

Sorry, I'm sure you are tired of people asking for things all the time, so I wasn't sure if I should post these or not, but I decided to put a few of these out there in case they were easy to implement.
These are mostly things that keep coming up as I work, rather than large new features.
1. The color picker. I can't say how many times I pick a color on the wheel and then paint, only to realize the value is much darker. Could the color wheel darken to reflect the actual color being picked?
2. A brush or option that will lock the brush at the angle that you start drawing a stroke with. This is similar to using A and Shift-A, but the rotation would remain free until you start a stroke. At that point, the angle stays locked until you lift the stroke. This would be very useful for brushes 7 and 8, to avoid the flipping that happens when you paint back and forth.
3. This would go well with 2,... a line that divides the brush circle showing the current angle of the brush. Similar to what is already displayed when you are using shift A.
That's it. I know you have big plans,... thanks for taking the time to read!
