I noticed the Take Control book is going to be free for all customers. Any news on this? I am a bit overwhelmed right now by DT3 and the book would help I think!
DEVONthink 3 is in beta testing, so the book would not be updated now. Outside the forums and support, there is the built-in Help and manual available.
I would not expect it to be published until the formal release of DT3 - too much risk of changes during the beta process. Also, it would be a little odd for someone to publish a user guide to software that’s not released
May 27, 2019—A major revision to this book is underway. We expect it to ship soon after DEVONthink 3 does, and it will be free for everyone who purchases DEVONthink 3.
