My bf and I used to be on Discord, but we've eventually moved to Signal for our private stuff.
One thing I miss from Discord is easy access to Tenor's GIF.
I've researched how to make stickers out of animated GIFs, but I've given up.
I have another solution.
I save the GIFs to a directory on my Nextcloud instance, and I can attach them to Signal messages both on my laptop and my phone.
