A fea­ture new to iPhone OS 4 (iOS 4) is the abil­ity to cre­ate fold­ers.  You can stack a few icons atop one another and they turn into a folder.  You touch the folder, it pops open, then you can touch an item in the folder to launch it.

BUT!  Did you know that you can place these fold­ers in the lit­tle fixed-4-icon dock at the bot­tom of the screen?  And did you know that the noti­fi­ca­tion coun­ters of the apps show up nice and big on the folder icon itself (as opposed to being micro­scopic 3-point font on the lit­tle icon)?  Well, now you know!

My dock now has one folder for a few social apps (Twit­ter and text mes­sages) and another for music (the iPod app, Pan­dora, and a few ambi­ent sound generators).
