first post is really outdated now, but there's some things I'd like to add now that AQ3D has reached that certain phase, and more tags should be introduced in accordance to this.
the beta tag mentioned above should probably be introduced now. something along the lines of 'pre-beta', and with the addition of "alpha" and the like. i don't think they need image tags, maybe just for alpha and use beta for all the current betas.
a 'removed' tag, in a magenta color. this will be used for content that has been removed completely, similar to the 'impossible2own' tag on the AQWWiki. if this is added, it will replace the rare tag on the removed content.
Implemented, tag is now shown on removed items.
a 'guardian' tag. doesn't need an image tag.
weapon tags- revised. it couldn't hurt to add the classification of the weapon itself. for example, the following tags can be used on weapons:
a 'freeplayer' tag, shows the items that can be obtainable without any purchase/kickstarter backing.
a 'backitem' tag, used to differentiate items that go on your back directly and filters out capes in general.
