Here are a few more features added since the last announcement:
* drag and drop of colors from palette onto gradient now works
* Shift+drag around stops to add them to selection
* When one or more gradient stops are selected, using the Copy command (Ctrl+C) copies to the clipboard the style (color and opacity) of the selected stop or the averaged style of several selected stops, not the entire object with gradient as before. This means you can now copy/paste style between stops: select the source stop(s), copy, select the destination stop(s), paste style (Ctrl+Shift+V). With several selected stops, this also allows you to easily average their colors and opacities by copying them and pasting the style back onto them. (After that, redundant gradient stops can be removed by simplification with Ctrl+L).
