I tested again with the navigation module enabled, and the problem doesn't exist, but the secondary toolbar gets a bit messy up the top

So i guess yes? you should make it a dependancy, I personally dislike (strongly) however not being able to set the menu to go horizontal, i've change the MR to check if the core_navigation variable is set in the template, to then include the file. that way it works either way.

Whats the direction that gin and this module are taking? it appears they are locking us into a vertical only menu?

I assume that the new navigation module is enabled. Can you test it with enabled navigation module. Currently I think we should add this as dependency.
