In fact this add-on is good enough, especially the JSON customized key map. Just one thing: pls make the movement, like j,k,h,l, as SMOOTH MOVEMENT, as well as Ctrl-B, Ctrl-D ! Otherwise it is a bit dizzy when browsing.... Thanks. 还是很好用的。

Another suggestion: if you go to google.com and press "f", there will be a label on the input field. But after you click according to the label you still can not input to that field. this is something you can improve. thanks.
