Suggestion!
From a hackers point of view.......
could you please amend your install instructions to replace a part of the navbar template instead of replacing the whols template?
Reason for this is because a lot of other hacks edit the dropdown menus for one reason or other. I can see a somebody stuffing up his board navigation (if it already hasnt happened) where he has previously edited the navbar and then followed your instructions and wiped the lot out
Please remember to only edit code where it is required, it might be easier to replace a whole template to add a hack ... but can undo others hard work.
Just a heads up
