Finding an application

I dont see why *which couldn’t be part of *help’s activity, then it could not only tell what module a command is in, but drop-through to checking the run-path for the requested command. *which is quite important at times, I sometimes forget that a command in the csd doesn’t take precedence over the same command in !Boot.Library for one example.
Maybe showing module paths could be useful too (assuming that information is available)
Edit: another thing one *which I used could do was to show the alias for a given command. Reading help for a command is not current if it has been aliased.
