Allow to select several gradient sliders
Sometimes I need to move several sliders in gradients at once.
I have to select them one by one and move each at distance I need.
I'd like to select several sliders and move them simultaneously.
Of course, they should be very clearly marked as selected, or this would confuse, if you forget to unselect them and then try to edit color for one.
