I am a newbie so maybe this is already possible, but I think a good idea would be to have the inactive players and players on the dl on the lineup and pitching staff page maybe in a drop down menu or already listed. You may not be able to make the changes there(or possibly you can just for the inactive players), but when determining a lineup or making changes with the rotation or pen you can see all the options you have and their stats without having to navigate to a different page.
