That's a long hard road. To make it happen I have to re-calculate and re-input every coordinates of every UI elements in the script, which is far harder than making Neumann Pro from Neumann, though it may sound counterintuitive.
And apart from that, In my estimation, simply shrinking the whole UI does not work well.
Ordinary skins are primarily adjusted for normal (or relatively small) displays. Small/large screen users have to compromise, but it's OK-level. Yet here large screen users have a small frustration that they have enough space to put more knobs, rather than just enlarging knobs.
MONA, on the other hand, took an uncommon way that aims primarily at large screen users. This is because Neumann Pro, which is also for large screen users, seems successful and I think this is the value that only third-party developers can bring.
But this comes with a price: For small screen users it can inevitably get cramped. The image below illustrates the situation.
That's how MONA achieved the great workflow without tabs. It is like a forbidden fruit in UI design...and that's why I show a warning message about the UI size on DEMO tab of the product page.
If I officially make small version of MONA, I guess I will have to make many adjustments or even reconsider some of the UIs. So it's beyond what I can serve as a "free update".
That being said, there could be a way to improve it without much drastic changes. I experimentally made 80% size background images for modules:

These are not the same as the images shrunk by a photo editor. These are exported directly in 80% size from my designing app so they are more beautifully rendered.
Can you please try replacing image files with these and use the skin with 80% zoom rate? Though not sure how u-he handles UI zooming, images pre-shrunk to 80% size displayed in 80% zoom mean virtually-100% zoom and could possibly bring a better (less jaggy) result. If this works it is a very good news since it needs no script editing. I'm gonna make 80% version of all images, as a workaround for small screen users.
