Looking for a program

[davidzthe1]

I am attempting to cook my 1st rom and am looking for a program that i don't know the name of, but is in several of the roms currently in use. The program that i am looking for enables you to see the open progams on your today screen and switch tabs to the open programs from your today screen. It reminds me of how windows allows you to minimize an open program, then click back on the minimized tab to re-open it. Anyone know the name of the program, and point me in the right direction so i can find it?

I have searched, but it is kinda hard to search for something you don't know the name of.

Thanks for any help in advance.
