Thanks for a great piece of software which really increases my productivity. I was wondering if there was a way to disable the roll over info shown on the picture below, thank you.

In Workshelf Preferences, select the tab General, click More Options and under Behavior select when or which information should be shown in a balloon.

I think that's a Dock and not WorkShelf. It's just that the OP has it set at the top of the screen instead of the bottom.

For a Dock:

1. Right-click on the Nexus icon > Preferences > General tab > More Options > Under the Behavior heading, click the pull-down and select the one you want > Ok > Apply, Ok.

Perfect, just what I needed
