PT2 just joined the original KS bunch 2 days ago, really delighted, kudos for getting the perfect thing back/out 
One little gripe I have is that… there are lots of good apps, and loading them from the watch itself is a bit of a pain to scroll possibly 20-30 lines down.
It would be nice to be able to have a launcher that combines buttons and touch to e.g use the buttons to switch between 9?12?16?-app pages, then tap on the app you want to launch for much quicker access to more than what you can do with quick launch button presses.
IMO it would be ideal if the SDK could expose a list of installed apps with a way to retrieve their name/icons/order in the stock list and launch them so that we could develop alternate launchers. That launcher would just be a “normal” app you can assign as Quick Launch, but which has the ability to present the installed apps in whatever way is deemed appropriate and launch it.
