Well I think that is a fantastic idea
I didn't know workbench was free to use tbh, which would make things much easier if that's the case...
My younger brother is a good case in point. He loved the Amiga and knows it can be emulated, etc. He had a quick look but got a bit overwhelmed with all the steps necessary to get things working, so has never bothered. I find this a shame. I know the "quickstart" option in WinUAE went some way to fixing this, but let's be honest, it's still all a bit confusing.
An EAB launcher/frontend maybe combined with ClassicWb (or whatever) and dead-easy host configuration or something would be amazing. One-click solutions and all that
