I'm probably asking even more than normal here but anyway :)
It'd be really handy if you had a little utility program that simply let you browse log files (.fbl5), showing all the information inside in the same format as the Build Log tab in FB. This would be better than trying to browse a massive HTML file (browsers hate them), and better than trying to use FB, which is awkward when you're trying to get to a specific log. You'd also be able to expand it to full screen, which is something you can't do in FB. Best of all, you could just double click a .fbl5 file (or even have a build launch it at the end) and away you go...
Just my Friday afternoon thought this week :)
