Well, not only would a cluster of number boxes, with the description
charts displayed on command, make a very clean and minimal interface,
it would also be very fast to enter information using the tab key to
cycle through fields. With the tab key, you don't need to put your
mouse over anything, which makes data entry much faster, as well as
easier, since you don't even have to be looking at what you are doing.
The more buttons and whatnot you put into the interface, the more the
tab key's selection has to cycle through to get to the next numerical
field, which slows down data entry.
Quite frankly, I don't see the need for a low-powered "beginner" mode,
given the expected user base of this software. True "beginners" aren't
going to hear about it or need it until they get beyond that stage
anyway, and more advanced users aren't going to abandon their SCMDraft
2 just to use StarForge in a mode that isn't particularly faster or
more powerful than what they switched away from. Readily available
correspondence lists, just a click away, ought to provide all the user
friendliness that is necessary, while still leaving StarForge with
something acceptably close to the fastest possible interface. A second
tier of tabs for user level, in addition to the tabs to switch between
player settings, units, etc. (hopefully including, well, everything),
would just create clutter.
