Better subscription filtering/selection

I don't know if this is a common user issue, but when you have access to a lot of subscriptions you don't care about, it's rather cumbersome trying to keep the selection of visible subscriptions clean, especially when signing out and signing back in.

For this feature request, we would consider two questions:

• How can I more easily select or filter subscriptions in the account management panel?
• How can I persist my subscription preferences across sign in sessions?

We may want to consider the following solutions:

• Simplify the UI by combining selection and filtering.
• Cache subscription selections to avoid having to select or unselect subscriptions again if signing out and signing back in is necessary.
• Move less-used but more complex subscription management to a dialog.
