1.
a) Use a theme that includes a command prompt.
b) Put one in the theme you're using (look for lsxcommand under modules at ls-universe and see the help file).
c) Use the !bang as an argument to litestep.exe (ex: litestep.exe !bang).
d) If it's a !bang you want to be running a lot, create a button for it with xlabel, and use an event (OnClick for example).
2. That's an old module and I don't know that theme.
