Looking to find a way to add a boomarklet for Mendeley and Papaly, dried dragging and dropping with no success. Below is a screencap of how it looks in Firefox [img]http://snag.gy/6EZYy.jpg[/img]
Sadly bookmarklets don't work on Vivaldi at this point in time. Doesn't matter where you actually put them (bookmarks bar / regular bookmark). Search the forums, issue has been brought up on several occasions, no idea when it will be implemented.
