As a user it doesnt make much sense to me to have the tag browser using Formats data from the database, but the Formats column retrieving data from the file system.

I primarily used the format column when I was organising my library, so handy in that circumstance. Personally I can live without it, but am more concerned that other users will also unknowingly slow down their Calibre by having the column.
The formats category is aggregated. It is right if any book has that format, not if a particular book has the format.

The column slows down calibre if you have a very large library and you do what you did (check show in tag browser) or sort on it. If it is 'just there' it has almost no impact.

My position is that I don't want to spend time on something that gives me negative benefit (extra support load). My 2500 book library doesn't have the problem, and in any event I don't have a formats column. Someone else who might benefit is welcome to take this on.
