I would second... er, third that motion about providing some zoom functionality. Some optional panel views would be great, too - look at what NI has been able to do with the B4II, even without having zoom: they balance that classic overhead B3 view against a couple of other, very non-traditional panel views which afford ergonomic access to deeper functions (not to mention easier patch access, ahem). You end up getting the benefit of, if not necessarily the best of both worlds.
But getting back to the zoom issue, I think it's a really good point to raise. I can't speak from experience with other Arturia instruments but, let's face it, that virtual CS-80 panel is spectacularly busy, even without the mod bays open. Couldn't Arturia justify the effort to provide some reasonable level of zoom functionality? That kind of very straighforward ergonomic touch is pretty standard in mainstream software of all kinds, and surely it's an improvement that Arturia could apply (and amortize) acoss the whole soft-synth line.
In fairness, this isn't just Arturia's problem - lots of plugins suffer from this kind of "locked-in" panel sizing. Whenever I see this type of inexplicable ergonomic "gap" in otherwise excellent software, I always feel like it's a symptom of a business organizational problem; it's one of the inevitable down-sides when you leave a dedicated team of geek geniuses to work wonders on their own, without ALSO having some irate, non-geek slob from the real world who can tap their collective shoulder every once in awhile and say really obvious things like, "That's a wonderfully authentic-looking GUI, guys, but what if not all our users happen to have their own electron microscopes??" Mainsteam software outfits actually have people who do this to the geek geniuses and, all things considered, the geeks probably agree that it makes good sense to have the reality check. Size of the company also has a big impact - note that the major DAW vendors tend to offer lots of ergonomic refinements and customizability because they know they have to cater to workflow in order to survive, while it's the smaller outfits making plugins or more "niche" products that tend (notwithstanding excellence on the technical side) to overlook or foresake these little touches that users appreciate .
