Enabling text selection in Quick Look through "defaults write com.apple.finder QLEnableTextSelection -bool TRUE" has been very useful together with QLStephen.
Ah, very nice! Any commentary on if it affects the speed of Quick Look in general? (I've noticed Quick Look getting slower in the last couple generations of OS X, and don't want to dog it down any more.)
In general, I don't see much of a difference. When you open files affected by the plugins, however, you're relying on plugin code, so things can change.
For example, I have an XML file that is 15 MB. Before I installed these plugins, Quicklook would take about a second to show it as a simple text file, basically. Now it takes much longer (about 10 seconds) but the output is nicely formatted (well, "nicely": it seems to fail pretty quickly on one CDATA node, so most of the document is not formatted correctly... but I digress). Clearly QLColorCode is adding a big overhead when invoked.
I'm going to try it out but you should definitely be on the lookout over the next few hours/days/whatever. I had to go thermonuclear on a Textmate QL plugin that was causing all kinds of trouble without being immediately obvious about what it was. That being said I'm looking forward to using all of these.
It'll give you information like whose devices have been added to the provisioning profile, the type of profile (e.g. Ad Hoc), the App Name and ID, and valid certificates for the profile.
