IMHO, the management part of the OG never really felt tedious, since it didn't take that much time in the end, even though you had to do it rather often. I'm repeating others here, but it indeed was a major part of the "small things" that made the whole organization feel organic and under your control. I'd imagine this impression can be reduced quite a bit by even small simplifications.
And I must say that I really like the quartermaster system TrashMan mentioned. It seems to strike a nice balance between having to buy your starting weapons (dumb for reasons mentioned before) and having the current unlimited supply of them (reasonable, but a bit boring).
