Manage Dash allows to unfavourite all scopes and leave you with a blank page

[Michał Sawicz]

Steps to repro:
* bottom swipe in dash
* unfavourite all scopes
* press <

Expected:
* forbid unfavouriting a single default Scope (Apps)

The same can happen if you uninstall the only remaining favourite scope, I believe we should lock the user in the Manage page.

[UX Comment]
'Apps Scope' can never be un-favourited now, marking as fix released.

[James Mulholland (jamesmulholland)]

Description updated with design solution:
"* forbid unfavouriting the last remaining scope"

This should be handled with a dialogue (shown at the point the user attempts to unfavourite the last remaining scope) reading:

'You must have at least one favourite'

and a single button reading "OK" to dismiss the dialogue.

[Michał Sawicz (saviq)]

The above solution won't help if, for whatever reason, the only favourite scope becomes available (it doesn't work after updating your phone, was removed from the remote scope server etc.). Any comment on what should happen in that case?

@Saviq

Having discussed this with the design team and proposed 3 solutions, we will be reverting to the earlier design where we have a single default scope that cannot be unfavourited (the Apps/ Ubuntu scope).

The scope can still be repositioned within the list when in edit mode (and by extension can be repositioned within the dash), but will not have a Star attached to it within the list (meaning it can never be unfavourited and the dash will always have at least one scope within it).

Will update/roll-back the design doc to reflect this change ASAP:

Hi, everyone! I unfavourited all the scopes in the old version of unity8 . After a while， I upgraded my system from 14.10 to 15.04 and got the latest souce code (unity8-8.02+15.04.20150109.2). However,I still have a blank page. Thus, I installed unity-scope-click. And then, the Apps appeared in the scope list(also installed), but I can't favorate it again. Changing to a new user will solve it. However, how can I solve it just in current user? Does any configured files existing in current /home directory ? thanks.
