This is under Smooth Sailing, which I also love for its many free text boxes, but I think most styles now are just the list, or the option of list/multi-level list/cloud. Having the info on the tag page itself is so useful for me, though, that I wish they all offered the option.

So an enthusiastic YES! from me for this suggestion. :)

[ETA] As per cesy's comment: the style in the posted screencap is a mixed bag on privacy.

If you were to look at my LJ tags page (you can, if you'd like--it's the same username), you'd not see any tags used only on locked or private entries. If a tag is used on a mix of open and locked/private entries, though, the table does give you that information. For instance, both "private" (only me) and "under the cone of silence" (only friends) are invisible to me when I'm logged out. But I can still see that "aha!" (mixed public/friends) is used on one locked entry.

It's not much of an issue for me, but I imagine it might be for others.
