"Shell layers" refers to "shl", which is NOT the same as DMD "layers".
Some people find "shl" useful; it doesn't require any special terminal.
Its main problem is that it merely multiplexes the terminal for several
concurrent processes, which have no way to tell what may be visible on
the current display.  A full window manager solves this problem.
