GEOFFREYALEXANDER  Thanks for the review; Undo has not yet been implemented for a couple commands as you noted; I'm revising the Read Me to note the exceptions; these will be cleaned up in a near-future release. As for the "Recents" menu, I've been working on that on and off for some time; due to severe issues with the underlying Apple Doc system, Diamond docs (no matter what format you try to save them) don't register as saved documents. Hopefully I'll find that solution before my ulcers kill me. Keep tracking updates here and hopefully I can have your issues handled soon.
