We have two separate threads for these feature requests, one for Google Contacts sync and one for Google Calendar syncing.
For now, we do not have an update on when we will release these fixes.
In the meantime, I suggest using a tool such as Zapier, SyncApps by Cazoomi, or Itduzzit to keep new contacts up to date in Nimble or Google Contacts.
More information about these apps can be found on our marketplace here: Nimble Apps Marketplace
Nimble added an integration for Zapier in January 2013. I have edited this thread to be only for Toutapp support.
If you want to get started with Zapier and Nimble, please go to www.zapier.com/zapbook/nimble
