A while back, I built a new standing desk using a Seville Classics rolling workbench as a base:
One of the nicest things about the workbench base is all the drawers. Projects that are not being worked on get put into their dedicated drawer. All commonly used tools are in the top drawer in easy reach. When it is time to switch projects, simply put one project away, and get out the next. This approach has greatly decreased desk/lab clutter and it is nice to have a fresh spacious workspace every time I switch tasks. Much better than the old approach with a lot more work-surface where everything was left set up all the time.
