As this was a sticking point last time around, I should just mention - 
the solution should have one single table for tracking bug changes, not 
two. If that requires enhancing the existing one, that's absolutely fine.

I think you may be confusing the fielddefs table with another one. 
fielddefs does not have a "Days since bug changed" column, it has 
fieldid, name, description, mailhead (which needs to die) and sortkey.

HTML accesskeys. And the answer is no; we're moving away from them, 
because most people don't use them, and they annoy many keyboard users.
