I love the E17 system and how configurable it is. I can also laugh at some of the basic functionality it still introduces after all these years. It's pretty amusing, after all. I still wouldn't use any other window manager. Suits me to a tee.
Mind you, I'm not much of a DnD type user myself. I've even turned off the EFM module on my system. Much prefer the command line for file manipulation and option setting.
