How to clean launch a GUI app via the Terminal (so it doesn't wait for termination)?

Some GUI apps launch cleanly via the Terminal command line.

Some don't, and they cause the Terminal to wait for the app to terminate.
...and even then, some don't "release" the command line.

The mysterious ampersand "&" suffix, seems to cause the terminal to put the process into the background... (but I'm not sure what happens there).

Is there a way to launch an app via the Terminal, so that there is no "hang on" effect? ... just like launching something via F2.

I'd like to have the command line available again, immediately (without something still in the background and writing out system message in the terminal).
