I use FARR on my own computer and, because I can't bear not to get use out of apps that I've paid for in the past
, I have appRocket loaded on my wife's notebook. Of course she doesn't use, but I do when I'm
tweaking it for her. On her computer it works flawlessly and with no perceptible hit on resources, while it kills mine! The difference is that I'm on three year old centrino with a gig of RAM and she's on a year old AMD Athlon 64+ with a gig of (much faster) RAM. Anyway, candylabs' website is promising big things in an upcoming update to appRocket, so I'm keen to see what they've got up their sleeves (the promises are somewhat empty in that they are only alluded to, not detailed)...
PS I think adding optional indexing to FARR will make it a killer app. I've long advocated keeping FARR simple and lightweight, but indexing is a reality and it's a feature that many people want. Keeping the core functionality of FARR available without indexing will allow people to choose how they use it. With massive harddrives and lots of RAM the norm these days, an index will hardly be a liability in terms of size and user-controlled indexing (over dinner, perhaps) should be almost imperceptible, if the user chooses to use it at all.
