amends round 5:
    Left right scroll is still dodgy
    Left right arrows should animate out once user has scrolled
    Benefits that a user has selected must maintain state – I.e. Stay selected if you leave and return to a category
Return to idle animation if user taps screen but doesn’t login (time out on welcome and log in)
If you select a hexagon and the child categories are should the other primary category should lighten or change slightly so its clear what section you have selected
