## TODO
## stats statistics when loaded or written
## report struct may not need to os, osver, and arch info anymore since we added stats
## signatures that went away feature
## annotation signature keywords
## click handler should ignore clicks if there's selection in the page
## popup panel layout (Fixed By and Notes) is confusing, and wide when it doesn't need to be.
## Remove reliance on version numbers? Need to get signature headers hooked up, and choose the latest releases for main reports
## build id (nightly / beta)
## linux distro information someplace
## clean up the startup crash icons
## better annotations support
## add dates to annotations
## improve signature header information layout, particular fx version numbers. We can easily expand this down and host info similar to crash stats summary pages.
## - filter graphing and the list based on clicks on the header data (version, os, arch)
