It would be nice to have the original name of a emote return if its been renamed when getting a channels emotes
Currently I would have to grab the channels emote id's and check it against every emote and it seems expensive when this is a simpler solution or i'm just unaware of a batch method?
Plus the web extension could match the web app with these screenshots?

This is already the case
Original emote name is contained within the "data" property of emotes within an emote set object
name is emote name in set,
data.name is original data
Worth noting perhaps that this is in api v3. not sure why you'd be using v2 but that data won't be available there
