Summary: Updates for lusty-explorer.el v2.4
> Version 2.4:
> * Add <code>defcustom lusty-idle-seconds-per-refresh</code> - wait for key presses in <code>lusty-file-explorer</code> for (by default) 50 milliseconds before initiating match window updates. Makes things more manageable for fast typers navigating directories having many thousands of files. Thanks to René Kyllingstad.
> * Consider buffer use order when determining the order of buffer matches in the window. By default, has a 10% effect on weighting. Fiddle with <code>lusty-buffer-MRU-contribution</code>.
> * Like <code>iswitchb</code>, give match priority to buffers not currently visible.
< * For iswitchb congruity, <code>C-s</code>/<code>C-r</code>: select next/previous match.
> * For <code>iswitchb</code> congruity, <code>C-s</code>/<code>C-r</code>: select next/previous match.

< Release 2.3 introduced:
< * Buffer explorer: put current buffer at end of matches list for more intuitive switching.
< Like iswitchb it should put all buffers on the current frame at the end of the matches.
< * Buffer explorer: sort first by fuzzy matching score, then by most recently used.
< The fuzzy matching score is a float, resulting from many calculations. Getting duplicate scores is nigh impossible.
< [new:sjbach:2010-07-05 16:31 UTC]
< Actually, duplicate scores are common in practice. I tested the float comparisons with various epsilons and decided none were needed.
< In my usage the last couple days about 3% of the comparisons had equal fuzzy matching score, so it's indeed not that uncommon. Though it still means that most-recently-used has little influence on the sorting.
< Bouncing between 2/3 buffers I often type the file extension, for example C-x b .py RET. This worked well with iswitchb, less with lusty explorer for obvious reasons.
< Another approach would be to turn the most-recently-used index into a number between 0 and 1, and multiply the fuzzy matching score with it to get the sorting index. Finding a good formula for calculating that number probably requires some experimentation.
< [new:sjbach:2010-07-05 16:31 UTC]
< But on the other hand, this sounds like a neat idea!
< * Buffer explorer: put current buffer at end of matches list for more intuitive switching
< This is not done when fuzzy matching is used, so the buffer explorer will suggest switching to the current buffer if it has a higher score than the buffer you'd like to switch to.
< [new:sjbach:2010-07-17 18:14 UTC]
< I have these implemented in devhead:
< * Put all visible buffers at the end of the buffer list (like iswitchb).
< * Turn MRU order into a factor in the scoring algorithm.
< Feel free to take a look. I'll put out a release once I've played with them for a while.

LustyExplorer is a fast and responsive way to manage files and buffers. It includes both a filesystem explorer and a buffer switcher through a common interface.
find-file crossed with
iswitchb or InteractivelyDoThings, but with a larger and more easily readable dedicated window for matches instead of the minibuffer.
Here's a 3.4 MB animated gif showing it in action (Note: 2.0+ uses fuzzy matching instead of tab completion)
After copying the file into your load-path, put this in your .emacs:
Launch the explorer with one of these commands:
M-x lusty-file-explorer M-x lusty-buffer-explorer
As you type a name, the list updates using a fuzzy matching algorithm. Press
TAB to select the highlighted match, or
C-p to highlight the next/previous match

iswitchb, give match priority to buffers not currently visible.
C-r: select next/previous match.
RETkey press, to differentiate from
TAB. Thanks to René Kyllingstad.
C-f: move highlight to next column.
C-b: move highlight to previous column.
C-x e: open a new buffer with current name.
C-x d: launch
diredat the currently viewed directory.
