Scroll through open tabs with the mouse wheel
When there are many tabs open, they overflow and one must use the arrow buttons to view the hidden ones, which is a tedious and time-consuming process.
When the mouse is hovered the scroll bar, the mouse wheel should scroll through the visible tabs, just as the arrows do now.
I use this feature very heavily in the programs that support it (e.g. Visual Studio, Sublime Text, Firefox, etc.), and it makes finding the tab I need a way faster and easier process than repeatedly clicking the left and right buttons until the desired tab comes into view. It would be great if LinqPad could include this functionality.
