Introducing TagViewer (officially)
Based on the fantastic work of inklesspen, TagViewer allows you to view the tags people added to a post while they were reblogging it.
This version is written from the ground up to not use the Tumblr API, since XKit violates some of their API rules, such as extensions not allowed to have a gallery (which would render XKit, you know, useless.)
It also shows the avatars of the user, and provides links to posts and searching for a tag right from the results window (opens in new tabs).
You can get it now from the XKit Extension Gallery. If you have the inklesspen version installed, you need to remove it first in order to install this version.
Since it is at version 0.1 Rev A, if you find any bugs, please let me know by sending me an ask. Thank you!
