Indispensible, have used it for years.
Only one flaw: Does not sync settings across devices. Only minor, but would be nice.

How do you run/activate other addon by using "Send message to other add-on"?

In Github there are 3 example but none show how to just run addon.

Simply amazing. Just a small flaw: would it be possible to have a command to find text on the page (Ctrl+F)?

pretty good，very convient！

отличное расширение, быстро привыкаешь

以前竟然不知道有這麼好用的東西，真是太感謝作者了

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.)
