Unfortunately, some other bugs have cropped up and I'm going to have to do one tomorrow anyway. So the fix is included. 
Watch out for v6.8.2 tomorrow, I'll update the release note in the forum when I've done it.
Its a pleasure to be sure.
I've lots more ideas even for the router.
Next release (v6.9) will have the ability to lazy-load the route templates as well as automatically unloading them. (And manually).
This will facilitate some interesting use-cases such as a building-wide collection of Kiosks all controlled from a single Node-RED instance. Where Node-RED determines what routes are shown, in what order and for how long.
It should also make it possible to have thousands (or more!) external templates such as for a WIKI or other Knowledge Base type use-case. Coupled with uibuilder's capability of displaying Markdown, that could be really useful.
I'm also thinking about ways to have >1 route display area on-page so that even your menu's could be routes. That would be yet another path to automating different menus and keeping the core HTML small.
Of course, with the uib-save node, it is now very easy to get Node-RED to update route template files. So menu automation could be done via a simple flow.
