Tabs

Feature Request:

I'm working on a complicated ground works project in the sense that the overall scheme (on a large site) is made up of a number of sub-projects. In order to make sense of the work, particularly for payment purposes I've created a lot of tabs. Having to click on a tab to reveal the "move left" and "move right" option is a right royal pain...particularly when you can only move it one step at a time. I'd like to request drag and drop functionality aka Excel. Also the ability to be able to copy a tab would be very useful.

Thanks

Kevin
