Thanks for the kind words, and I'm glad you're finding Virtualmin useful! We certainly try to provide the best support in our industry, and when we screw up we apologize and do whatever we can to make it right. The bar for support among market leaders in our industry is pretty low, but I think in an area this complex, great support can be a very good differentiating feature. So, we're never tempted to think, "Well, we're providing way better support than Plesk or cPanel, so we can rest today."
I've got a todo list a mile long for things we could be doing better, but we're getting there.
Magic happens. Not an iPhone app, but an iUI based theme that works really well on iPhone, and pretty well on Android. We do actually have plans for standalone apps, but it's an area where we're not particularly experts...so it might be something we have to outsource (which we tend to avoid for programming stuff). I've just bought a Mini 9 for Hackintoshing, so I'll soon have an iPhone dev environment, so might give it a try.
