I've used this extension since its early days. I'd tried others, but this has evolved a better interface. I have one suggestion: when a conflicting (ambiguous) gesture is found (two equal gestures for different actions), the extension tries the older action first, then tries the next. That could be an actual feature: same gestures should be executed in the order they appear in the list (the gestures would have to be shown as an ordered list for that), maybe adding a "break" option to stop the execution at a certain gesture (e.g., a single gesture could trigger a Save Link and a Save Image, in that order, but if the image was a link, an option could prevent the image from being saved.)
