Hello! I've a trouble. Top vertical toolbar overlays and hides right scrollbar upper part. So could you shift upper part of scrollbar down to unhide it or shrink the vertical toolbar to the left? I like this extension a lot! Very helpful to me!

This is exactly the add-on I was looking for!
The only thing that's missing is the ability to navigate (per page, chapter etc.)

Browser are now the center of the computer usage nowadays and it is good to be able to open ones file without installing or loading hosted apps.
Keep on doing the good job and THANK YOU for sharing
