FWIW, if this does get done, can they _please_ not be re-arranged in the tags, and by extension, the filenames? Hopefully there is a way already to _only_ color tags in an easy-ish way without shifting their placements if there isn't already. I know I'm not the only one with years of saved images that'd potentially get re-saved since they don't share the same filename.
~~Another tidbit about shipping tags: not sure how, but hopefully there's some way to also allow searches for ship tags in a simpler manner. ~~As an example: To find TwiJack, Twilight+Applejack~~ I realized this very moment there is in a roundabout way. [`implies:twilight sparkle, implies:applejack, implies:shipping`](/tags?tq=implies%3Atwilight+sparkle%2C+implies%3Aapplejack%2C+implies%3Ashipping). Just found out though that the [shortcut tags](/tags?tq=implies%3Ats%2C+implies%3Aaj%2C+implies%3Ashipping) don't work on that.
