I wish you'd stop telling us what we need. I've already expressed it here clearly enough, but I'll do it again: The only way to find a specific file in Mp3Tag is to use a filter. But when you clear the filter, the file display jumps back to some other place in the collection. There should either be a real Find function OR the ability to tell the program to show the selected file after the filter is cleared.
This is a shortcoming of Mp3Tag. Looking at the results of the poll, users of the program don't really want a Find function or a workaround using the filters. (On the other hand, 50% of the responders DO want one ;O)) Unless, of course, the poll hasn't functioned as a poll becase it's too full of comments from users who don't want one and who are determined to convince others they don't need one...
One gets the impression, reading this forum, that the program's users feel that it is already fully formed and needs no additional functionalities - not "bells and whistles," but real, useful, basic functionalities, such as opening a second instance or... a Find function. Its many excellent features, as well as its shortcomings, they seem to feel, are as immutable as the laws of science or the dictates of the Creator, depending on which point of view you take. One must bend to them or simply find another tagging application. Unfortunately, there is none that even comes close.
Forgive me for being somewhat provocative, Comrade, but I'd like to get a real discussion of this failing of Mp3Tag going.
