favedeck by nedo(xff)

favedeck (stylized in lowercase) is a browser extension that adds "decking" functionality similar to Pinterest's boards for Twitter bookmarks.

Features:
- Deck tweets: upon pressing the bookmark button, you'll now be prompted to add the tweet to one or more decks.
- Organize: the "Bookmarks" page is now the "Decks" page. Here you can view, reorder, and explore the decks you've created. You can also view all bookmarks as you normally would by pressing the "All bookmarks" button, or create new ones by pressing "New deck". Tweets inside decks can also be reordered, "undecked" (removed from said deck), or added/moved to other decks.
- Private, really: favedeck makes zero requests when decking tweets. Everything is stored locally. It's also possible to export decks if you wish to transfer them to another device.

favedeck is open-source software and the code can be found here: https://github.com/nedoxff/favedeck
