Write.vim

Although Vim is naturally optimised for writing software, I actually use it as a general purpose editor for all kinds of writing. Write.vim (GitHub: Soares / write.vim, License: Vim) by Nate Soares is an attempt to cater to this need. When in "writer mode", set by typing :WriteOn, Vim is configured to move screen-wise, hide line numbers, and turn spell checking on.

sha3.vim

There's been a lot of talk about SHA-3 recently, since NIST announced that Keccak has been selected as SHA-3. sha3.vim by Yukihiro Nakadaira is a port of Keccak-simple32BI.c to Vim. Saving gist: 3848180 to ~/.vim/autoload/ will install it, and SHA-3 hashes can be generated with sha3#sha3_512('foo').
