Mine is playing with errorformat (personal blogspam: http://flukus.github.io/vim-errorformat-demystified.html http://flukus.github.io/vim-errorformat-demystified.html) and combining this with :cf (read errors from file) or :cb (read errors from buffer) to parse a file/buffer into the quicklist. Great for dealing with log files.
