is there another way to expand part of a palette to a whole palette?
That would be so handy to have a button to do this! I have been able to expand the strip viewer but it was by accident and I'm not sure why it happened.
Here is another resource for working with gradients. If your gradient is very simple, you might be able to use ApoMap. Download and install ApoMap, found here:
As far as I know, ApoMap also lacks the ability to stretch out the gradient. but it has a fun window (Graph) where you can the proportion of RGB at each position.
It just makes it a little easier to see what color is happening on each position.
You can look at an ApoMap tutorial at deviantArt.
