CloudStalker could not agree more.
He has an idea for this already posted. Here:
[#5] Queue Up Items.... (Scroll down to #5)
The basic idea here is that, depending on the order in which you've clicked the
+ button, items can be queued and accessed via the Media Library (filter). So even you don't want to save a playlist you can still queue items in the playlist and have them play in the order in which you're queued them, in theory. Did CloudStalker just reapeat himself?
Hopefully today CloudStalker will post some other idea he has for the playlist in the QT4 Consolidation Thread.
Note: CloudStalker needs a laptop.
