As of late February 2004, the BFAV has a redesigned reviewer notepad and a very nice tabbed UI (thanks Ken!). It's pretty usable now. Finally :)
The BFAV 2.x series of releases is approaching stability at which point it will be a maintenance project with only incremental enhancements. The BFAV 2.x series needs a maintainer, or team of maintainers, willing to manage fixes and incremental enhancements submitted for the BFAV 2.x from the Squeak community.
