Tried to imagine how a wallet that is as simple as possible would look like:

Please note, that I am not a professional UI designer, nor do I belong to the dev team. So it's just a random DRK fan's quick scrabble just for fun.
Private funds section has both Spendable and In Progress, because imo the anonymization process should be able to have part of the denominations fully anonymized and ready to be used (gone through required rounds already) while part of the funds not. This could happen when some of the denominations have found mixing partners very fast, while other denominations have not. Or, the user has decided to anonymize some more coins while the previous ones are still denominating. Or, the user has sent private coins and the "Amount of Darkcoin to keep anonymized" threshold has been hit.
It should contain as little information as possible. For example, unless there are unconfirmed coins, Incoming balance shouldn't be displayed at all, i.e. no need to display "Incoming: 0.00 DRK".
Likewise, if the anonymization process is not running, In Progress shouldn't be visible.
