Hello,
I've created an issue for the double-click action:
https://github.com/fastaddons/ScrollAnywhere/issues/40
I will look into it for the next release.
Have a nice day :)
Best regards,

Hello,
Check the Options page - there you can set what button should be used for scrolling and you can test there how it works (in the right part).

Hello Sofia,
This addon is meant to be used with a mouse. So if you use touchpad on your Mac, then it's not gonna be useful.
If you do have mouse, make sure to visit Options page where you can setup what mouse button is used for scrolling and where you can test the scrolling (in the right area).
If you have more questions, you can contact me directly on my support email.
Best regards,

Hello,
I'm not sure I understand...
Could you write me email with more details?
Also, by default the addon emulates dragging scrollbar - so on long pages the speed will be faster. But it can be changed in the Options page.
And second question, was this working before? I released new version recently so maybe I've broke something...
Best regards,
Juraj Mäsiar
