I been using Today Plus for a while now.
It does seem to hide your individual email account icons by DEFAULT.
There is no way to change the date on the home screen calendar reminders. I guess it's european thing.
You cannot change the home screen Messages, Call Log, & Calendar display, those are there to stay. You can however, change the bottom 5 icons. To do so, just hit the Menu key from the Home Screen...and move the icons you want on the home screen, to the top row. To move them, select the icon you want, hit Menu Key, and select move, just trackball it over to the top, and hit the trackball. Once you are done, hit the Back Key or End Key, to view the Home Screen again, and the bottom will display the 5 icons you had on the top row.
