Well, let me be the first to mention what most people jump in with early.
Ahem.
More windows-like.
OK, I want to say that I really like the look and feel of the current interface, which some people don't care for. I really agree that the interface for SE5 should be distinctive from the OS environment.
But I do want when I click on the scroll 3/4 from the bottom, the list to jump 3/4 of the way, not to the bottom.
I do want the page down key to jump to the next screen full, not the bottom.
I'd like mouse scroll button implemeted.
Overlapping windows may be a good idea, if implemented well. I have every confidence that you and MM can do it well. But the endless overlapping windows was what I hated about Outpost.
I'd like to see some examples of what you're working on so I can give more specific comments.
Oh ... one more thing ...
You're working on SE5 already? Wow! You guys sure are diligent about pleasing your customers.
I thought you'd coast at least one more year. If only every software developer cared as much.
