The branch at http://github.com/ketan/rack-bug/tree/filter-panel contains some support for rendering the timings on rails before/after/around filters.
I understand that this may not quite be upto any rack-bug standards, so I'm open to any feedback to help improve this patch.
Thanks for a great plugin!
Add support for a panel that renders time for each filter.
Any chance of fleshing the specs out a bit more?
I'd still merge this in happily with a few more specs.
