As the title says, have a feature to do a quick screen recording and save it as a gif, similar to ShareX feature. Like in this video using ShareX (video is loud). https://youtu.be/2nWR4ZdXxSo?t=36
I would also love such kind of implementation. Under Windows I am using ScreenToGif very frequently and I think this would be a great addition to Spectacle. As far as I understood there "just" needs to happen an additional step after the video recording which takes the frames and creates the GIF out of it. So for example if using ffmpeg would be an option a simple ffmpeg -i "$source_video" -filter_complex "fps=15" -an "$output_gif" could do it.

The MRs I linked also add support for animated WebP, which is a vastly superior animated image format.
