From an admin standpoint, I use that list to do new tagging, and also to check old tags -- adding choral vocal parts that weren't necessary when we first started tagging, etc.
As it is, if I go away for more than a day, the new ones drop off that list, and now it seems like what Kalliwoda is saying is that I can't even do this morning what was done in the last 24 hours. I was completely up to date as of 18 hours ago. What he is suggesting would really help me keep up.
BTW, I do use the untagged pages button, but since many of our long-standing problem pieces are sitting there, I find it more useful to do the recent uploads first, and then if I have time to tackle an old one, then I'll go to the untagged list.
