* 1.1: Spec describes toolbar which may not be possible given the application framework we're using. In particular, issues with the spec include the color, logo and different font weights may be at issue.
* 1.2: Spec's treatment of FxA UI may be difficult to match. We should use the default OAuth implementation and re-evaluate UX once we see an implementation demo. Also, the landing page UI should display a log-in CTA directly and not require users click into the the hamburger menu.
* 2.1: MVP will only include file picker. Signed in users will be able to select multiple files. File selection flow will be Android-native. Probably don't have the ability to add notifications as in the last screen on this page.
* 2.1: @fzzzy will provide screenshots of this flow for UX evaluation and comment.
* 3.1.4: The spec shows deleting the last item in an unshared set returning the user to the picker menu. Instead, it should return to the app home page.
* 3.1.5: Same as 3.1.5 notes. Both cases should show the warning dialog.
* 4.1: We may not be able to do a thumbnail here. Instead we should specify a set of icons to be displayed.
* 6.3: We're not going to allow cards to be edited. This page is deprecated.
* 6.4: Swiping cards to delete is stretched.
* 6.5: We're not 100% sure what happens on network connectivity errors, we should test this and adapt UX as necessary.
* 7.1: The last screen on this page depicts a network error notification on the selection screen. Instead the user should hit the send button, be taken back to the cards and display the card as in 5.1.2
* 7.3: May not be necessary...we can ask for permissions on install.
