Ok let me explain a a bit. The On imgur you can favorite picture's and gifs. buut there is no easy way outside of imgur to post so I was thinking. What if you'd would take something like the Gboard and modify it a bit to support imgur. You could link your account or it could you could give it a username and it'll grab the the folders. Then you can select a default folder or it will default to a folder that it is.

Then i Then in then in any app you would want a reaction imgur from imgur you don't have to open imgur and grab the link from there. You could just do this from withing your your keyboard. The app will just have to put the link in and it is done.
