I think _generic.help.html is simply gorgeous, but
clicking on 
(list) for the superseders field in a tracker with 3K
issues 
a) takes a good 20s or so to load,
b) results in a window that randomly blanks sections of the
    window, if it doesn't blank the whole thing (in
Mozilla) 
    (see screenshot).

Perhaps other browsers are fine with a 1022K table, but it 
does seem a bit much .. 

Solutions: batch the popup? Give the popup files where to
enter the kind of batch you want? (Eg. 1000-1500 in batches
of 100).
