I like to see a new feature in Adobe Kuler. Kuler allows us to create custom color shemes ignoring the rules such as analogous, monochromatic, triad etc. But once we swtich to Custom rule, all handles will start to move freely and there is no option available to lock the handles and then rotate to define more schemes based on the same custom rule. It will be even better if we can save a particular rule as we save the color schemes.
+1 for this. There should be a lock next to the colorwheel which would freeze or unfreeze the position of the arms so that one could first set the color positions in custom-mode, then click the lock and be able to rotate the entire setup (rule) around the colorwheel, as is possible with the other modes.
