• IndexedSearch - when you do searches will show you "Match 2 of 4" in the status line
• delimitMate - automatically closes quotes
• SearchComplete - tab completion in the / search window
• syntastic - automatic syntax checking when you save the file
• repeat - adds . (repeat command) support for complex commands like surround.vim. i.e. if you perform a surround and hit ., it will Just Work (vim by default will only repeat the last piece of the complex command)
• endwise - automatically closes blocks (if/end)
• autotag - automatically creates tags for fast sourcecode browsing. use ,f over a symbol name to go to its definition
• matchit - helps with matching brackets, improves other plugins
• AnsiEsc - inteprets ansi color codes inside log files. great for looking at Rails logs
• solarized - a color scheme scientifically calibrated for awesomeness (including skwp mods for ShowMarks)
• Airline - Improved status bar. Requires patched fonts (installed from fonts/ directory)

YADR provides solarized enhancements that make it even better. If you're using another theme, you can disable them with this line in ~/.vimrc.before:

let g:yadr_disable_solarized_enhancements=1
