It occurred to me today that Square has a relatively easy workaround available to the lack of glamour plates: macro slots.

All it would take would be a new command:

/glamour <item> [<hand>]

Applies <item> as a glamour over your current equipment. You must be in a major city to use this command. <item> must be an item in your glamour dresser or armoire.

If <item> is a ring, <hand> must be either "left" or "right" to specify which hand the glamour applies to.

This wouldn't be a perfect substitute for glamour plates as it would require dyed items, rather than being able to use dyed plates. But it could certainly help a lot, since you could then use macro slots as pseudo-glamour plates.

It would also be nice to have /dispelglamour too.
