In the Enscape 2.8 development agenda it is mentioned that "Custom Asset Library Import" is a "Stretch Goal".
That post was last updated in March, and the ETA for 2.8 is end of June, so I wonder what the status of that feature currently is.
Personally I think this is the most important feature by far compared to everything else mentioned in the development agenda for 2.8.
The reason I am asking now is because I am debating whether or not to create a custom library based on Pieter's Tutorial, or if I should just wait for a month or so for the official Custom Asset Library Import.
