I really like the FuzzyFinder vim plugin. In short, it allows to search quickly for files, tags, buffers, etc using fuzzy logic.
I especially like it for its ability to find files recursively using simple patterns. However, by default FuzzyFinder is not really convenient because it searches for files relative to the current working directory in vim. And what I want is to be able to search for files recursively relative to some project’s root directory at any moment from any buffer.
Of course, it’s possible in FuzzyFinder to use “../../**”-alike patterns in order to make it search recursively starting from upper directories. But it’s quite boring. It’s especially painful for those folks(me included) who have vim settings which change the vim cwd to the one where the opened file resides.
