Great idea, this app will be very useful in a grocery store where you don't have to pull your phone out to check the groceries list, but then put it back to have your hands free, then pull the phone out again ...
I have installed it on my phone, I got it to work, I have two observations/feedback:
1) if you get to the Google authentication screen but then, for some reason, switch to another app, the login screen cannot be reached anymore. Trying to get back to it via the Settings (wheel) button in the Pebble/Watch App, won't bring the login window back, would just show a message saying "Launching app on watch to complete configuration ... (PebbleNotes)"
I tried to uninstall the PebbleNotes and kill all the phone apps I thought were involved (Pebble, Chrome), but only a reboot of the phone allowed me to be able to get back the login screen.
2) I have indented tasks in my Google Tasks (eg: small trees). It seems that the PebbleNotes shows all the leafs first, then the major branches.
It would be nice if it would obey the structure as it is.
Thank you for your work!
