DARKENTRIES  LiteSwitch X by Proteron is an excellent replacement application switcher. It allows you to exclude applications from it, even if they do show in the dock. Looks like MacUpdate has a special deal on it for the time being.

(Version 1.2)

DARKENTRIES  Great app. Simple to use and versatile.  
(Version 1.0.1)

DARKENTRIES  Good deal on this. It's a great application, but it's lacking a few things I want in the way of a timeline app.  
(Version 1.1)

DARKENTRIES  i've been looking for a good mindmap application lately. I'll have to give it a shot.  
(Version 2.0.2)

DARKENTRIES  great utility. support for more than just safari is what makes this app ideal.  
(Version 2.4.13)

DARKENTRIES  This is a nice library app. The ability to import from other libraries, including DL, is a great timesaver and makes it easy to decide to adopt this over DL. The developers appear to be very responsive to bug reports and feature requests. The biggest thing this application has over DL is the extensive breakdown of Music information. I much prefer this implementation over DL.  
(Version 1.0.8)

DARKENTRIES  This is the first I've tried it. It's speedy, even on large directories on an old quicksilver g4.  
(Version 3.0)

DARKENTRIES  I tried this one not too long ago. It's a pretty comprehensive tool for searches and saved searches. A lot of thought went into this app.  
(Version 2.0)

DARKENTRIES  This is pretty nice, and the growl support is a bonus.  
(Version 2.7)

DARKENTRIES  This is a great organizational tool for a video collection out of control. Well thought out and implemented. I've tried it out in the past, but couldn't justify the price at the time. Looks like a good time to get it.  
(Version 1.8)

DARKENTRIES  neat tool. i could find it useful, but not an absolute need.  
(Version 1.0)

DARKENTRIES  Good too. Not even a bad deal at full price, but I gotta say the sales pitch "tak you another five seconds if you weren't using MacDust" isn't very convincing.  
(Version 1.5)

DARKENTRIES  I've tried this in the past. I liked it, but I couldn't justify the expense as it's not a huge need for me. Very slick little app, though.  
(Version 1.2.2b)

DARKENTRIES  interesting  
(Version 3.4.4)

DARKENTRIES  i'm just starting to look at backpack. the big downside for something like that is the need for connectivity ever time i want to access my data. this looks like a good solution.  
(Version 1.3)

DARKENTRIES  I'll have to add my Ditto to the rest of the critiques below. I jumped on board with Scivener Gold then transitioned throughout the open beta program. It's met all my needs so far: stable, quick, flexible and aesthetically appealing.

Scrivener has several features that I never thought would be useful to me until I actually used them. The corkboard and outline features, and the Edit Scrivenings feature. The Snapshots feature was a requirement for me. I like to have built in version control. Rich Text and the Multi Markdown option is a bonus.
