Let us be able to go on a browser
To download a gif from tumblr. I'm on my iPhone whenever I find an awesome gif from tumblr that I wanna save. You can reblog a gif into your blog on Tumblr, and so if you allowed us to find our blogs and gifs on a browser (directly in app, or like have an option on the tumblr app/safari saying "download to Giffer") it'd be a lot easier to download them.
This kind of already exists in the new version of Giffer Pro (and regular Giffer too, as soon as Apple approves it – hopefully sometime this week.) All you have to do is hold your finger on a GIF you like in Safari, choose “Copy” then in Giffer, tap the down arrow button on whichever folder you’d like to import it to, and select “paste a gif”. Hope this helps!
