Who on this forum wouldn't want to beta test
Anyway, beta testing isn't that easy if you take it seriously. I did it once for a game and i remember it was quite tedious at times. Off course being able to play your favourite game before it's released is really great
And being a programmer, it was also fun for me to think how the programmers pulled off certain things.
As to what i want to see changed in SE5, 2 biggies:
* being able to assign one ship as the succesor of another in the design view so that you can upgrade all ships of type very easily without looking them up and clicking and clicking. All this clicking to upgrade prevents me from spending more time coming up with devious schemes to become supreme ruler
* lists should remember their position (some already do now)
