Will it be possible to make plugin files for Sherlock is this a simple
html/text files or a certain type of file that could be compiled if
replacing APPL with whatever code it is. For example lets say there is a
search engine someone uses but this certain search engine has no plugin
for Sherlock.

Oh and a note on replacing APPL, I've done that before already, my old
program called ControlDown 1.0 is not a application program it is a OS8
Control Panel of type APPC
