The biggest time saver I noticed is a suite of vim functions I wrote to run rspec.tests in rails projects. I can easily run a whole spec file, a specific test (via line number) and run failures with leader based commands in normal mode. Saves significant dev time and avoids the slow down of switching to the terminal and writing out the commands.
