You can store the videos, images, and gifs, share them and/or,
create a meme from the them, the world is your oyester.
Download videos and images for gifs, gallary tweets, quote tweets, normal video and image
posts and even the preview images for links, it can handle it
all.
I found the other twitter video and image downloaders kinda sus, thus, an open-source tool for downloading twitter videos and images (la pièce de résistance).
