Just to quickly mention: although GuyPerfect has been kind enough to let me download his excellent L2 editor, I still keep copies of PCL2ED and PCL2STAT in reserve, because of their functions with objects like cannons and swingchains, etc. Also, PCL2STAT allows longer level names. On the other hand, GP's editor is much better at handling terrain.
So, personally, I find it useful to use both pieces of software. In other words, I believe that there's still room for PCL2ED in the embryonic Lemmings 2 customisation community.
