Personally, I prefer DOpus4, but this is great news all the same. When there's a release, I'll probably pick it up purely for the sake of supporting further development. Who knows, I may even like it! :-)
Some thoughts:
-A DOpus4-style mode would be nice (one full-screen window w/ 2 panes) :-)
-The Workbench replacement mode made sense back when it was developed, since the Amiga OS was in stagnation at that time. Now, however, it doesn't seem as important. A Workbench *integration* mode, like in the Windows version, would be better for the current state of affairs.
