I like the very clean design. I get annoyed with some of the flashy plugins that have tons of options, get really complicated, and are 10's of KB in size. This one is simple and clean. Well done.

One a site note... for the duration example, is it possible to make columns to line up the time and duration in columns rather than just with spaces? I have some auto-suggest code where I'd like to make two columns that are aligned rather than just with spaces.
