Show list of services rather than providers in 'Add an account' section
Current Add an account section displays a set of providers/services to choose from. But there are always more providers to add.
To limit the number of list items in Add an account section and still have many more providers, please display only services in Add an account section. Also please do not use protocol names, for eg., use 'Email' instead of 'IMAP and SMTP'.
For already added accounts, current method of listing by provider is okay.
