During season, you can pretty much do what you please. I, too keep my rosters exact. You can control every team's starting lineups, pitching rotations, minor leagues, make any trade you please, etc.

You basically control everything, which is great if you want to keep up with the real life moves.

About the trades, you put in a trade offer to a team, then switch to that team you offered to do the trade, and accept.
