More detail is available but a short description is:
1. Adding more tags than fits causes the tags to scroll to the left to make room, and the new tag drops in at the end (this is correct). Deleting a tag when there are too many should cause the gap to close up and tags to scroll back to the right, until no tags are hidden off the left hand side. Example “Brands”
2. When there are too many tags to fit, an icon tag (see screen shot) should appear in the left of the tag area. icon file is on server as LiveWebs/aquagear.us/www/images/ico
3. scroll wheel over the tag display, when there are too many tags to show, causes the tags to scroll one tag over for each scroll wheel step. (not a free scroll). Adding a new tag causes all tags to slide off the left again if they have been scrolled, except for the latest ones.
