After having read that QuickSilver was no longer supported by BlackTree and has since gone open source, I noticed more and more people switching to/suggesting other app launchers i.e. Buttler and LaunchBar.
Is QuickSilver still relevant? Has anyone experienced any instability since it's gone open source?
It still runs stably for me. I would be miserable without it.
And yeah, I would recommend switching if you only use it for an "app launcher", but launching apps is like white belt Quicksilver. I don't know of any program that lets you simply tell your computer what to do in such a simple way. And even Spotlight won't remember the keys you usually type to identify an object or action.
Ubiquity for Firefox is pretty good, but it's locked inside a browser...
I haven't used OS X in a while, but the impression I get is that Spotlight has largely negated the reason for using a launcher in the first place. Quicksilver has some cool things like direct objects built in, but by and large it was mostly used for launching apps, and Spotlight can now do that just as fast.
I use quicksilver all day (on latest version of OSX); and no spotlight doesn't negate it... quicksilver is still much faster for launching applications.
I also gave up on QuickSilver for a while when Leopard came out. I tried Spotlight. I gave up on that and returned. QuickSilver is much faster, and it does so much more that I missed.
I have not noticed any instability (Leopard) running B54 (3815) - it looks like the open-source version is B56A3 though.
QuickSilver is awesome when integrated with Parallels/VMWare Fusion to launch Windows apps too. You don't get the deep integration as with the various OSX plugins, but it definitely helps the dual-OS usability.
Quicksilver is still alive and well. There are at least a couple of endeavours to keep it going, up to date and restructure and clean up the code base. Check out the code from Google Code.
As for launching apps, not even Spotlight comes close to how fast it is in Quicksilver.
Of course the real joy of Quicksilver is past just launching apps and using triggers, scripts and the many plugins. My workflow goes to a new level with Quicksilver. I'd be lost without it.
After Quicksilver stopped being updated for a while, I migrated to LaunchBar. Quicksilver had some occasional crashes and could be very resource intensive. LaunchBar has largely the same functionality without these problems. It is not free though.
I didn't know Quicksilver wasn't being as actively supported. It does all I need it to do at the moment though.
Just installed LaunchBar but I can't set it to be Option + Space to "launch", I can't deal with it not using that, I'm too use to Spotlight on Command + Space and Ctrl + Space is for VS 2008 :P
The one thing I do miss was using QS to quickly send attachments via email to people in my address book. Highlighting the file, activate QS, Current Selection tab Mail to.. tab Person's name was just awesome.
After the 10.5.5 update, I find Spotlight to solve 99% of the things I originally used Quicksilver for and the speed is nearly identical now. Spotlight is invaluable for finding information you may not remember where or when you last saw it. Unless a major rewrite of QS causes me to reevaluate it again, I suspect Spotlight will be all I need and use.
There are a couple branches out there that are active, I think I'm currently running B56 and loving it. I have too many scripts, triggers, objects that I rely on daily...I would be lost without it.
