Tool nesting groups
I'm on a laptop. With the nested tools off to my right you can organize them to be in little clusters when you use them. Its great. When you have the three window options for color / gradient / swatches it would be nice to be able to click and drag a swatch onto the tab of one of the nested sets for a second and have it switch to the underlying window. For example, you drag a swatch square onto the gradient tab and then you could drop the swatch color right into the gradient slider. Now, you have to have 2 separate tabs to perform drag and drop. Anyway, the program is awesome and I have loved it for years.
Josh, just tried, and was able to drag and drop the swatch from the opened Swatches panel to the Gradient panel behind it, just hovering the dragged swatch at the caption to let the other panel to open.
Does it work for you?
