Hello,

I had the same problem with my own plugin therefore i create a setup 
that can be change on installation

You can make setup confgurations in:
ext_conf_template.txt

With the line:
# cat=all//20; type=boolean; label= Autoloads mootools : Loads Mootools 
javascript on the page.
mootools = true

You can turn mootools on/off for that plugin.

Hope this helps

Greetings Gijs
