I am also looking for this function- I have a meeting with a client and would like to look at photos at her house. Honestly it seems as if the ideabook I spent time putting together is useless at this point.

Hi Oliver, Thanks for the feedback. This feature is no longer available in the app, but I have let the team know that it is sorely missed!

Hello. Requesting for this feature to be restored!!

Saving idea books for offline viewing is a must. Many areas do not have mobile internet access. Particularly construction sites. Please restore this functionality.
