In current version its not easy to do without caching (basically the sql query would be very slow and without caching it would cause high load). In version 3.x however it will be easy (the tag system is different).
All tags module I've seen on websites and also one I wrote for other adult script display about 1000-2000 most popular tags on dedicated tags website page, usually sorted and available to filter by alphabet letters.
And this makes such module rather not possible to have for public video script with multiple different languages support, multiple non Latin alphabets, or even tags using multiple different set o characters on same website.
I wonder how do you Symtab plan to manage it?
...or such tags are not sorted by any factor... but this doesn't look elegant.
I've changed the database design for the tags. There is a tag table now (that has all tags, for everything, video, photo, games...everything) and data from this table can be sorted easily by times viewed. It can also be translated to other languages easily.
