As you know, Steve, I've just joined the ranks of the Green and Black army with a big-size Domino. Nice bit of kit; now only need to learn how to use it properly!
Re-read this with great interest, and have started looking for my box of screw cups already - it's simple but highly effective, as the best ideas usually are.
And it would also help, possibly modified slightly, with biscuit jointing, too: As an experiment, recently I made a trolley for my P/T, biscuiting together three layers of 18mm MRMDF, but in 25mm wide L-shaped pieces (it makes a tall rim around the platform that carries the castors). I wanted to plant #10 biscuits carefully, so the two joins didn't bump into each other:
I like biscuiting with the base of the jointer on the benchtop, as it helps me avoid skidding issues (I can already see that the Domino is loads better in this regard, because the front handle is on the fence, rather than the moving body of the machine - what were Lamello thinking originally???). I ended up with a rather awkward ad-hoc support arrangement to hold the workpiece still while I cut the slots. This idea (or similar) would have been loads better.
