Libraries could be so much more useful if usergroups existed. Lets suppose a weekly grocery store circulars is done in InDesign. Lets says there are 110 food categories of which we want a library fore each category and we have 55 users who need access to the library. Once the libraries are created, would take 6,050 clicks of the invite button alone.
You can enter the emails with colon delimited separation which can cut down my clicks of the blue button to 110 if typed perfectly in a text file without a single error. When a new person is hired once again another 110 clicks to share and toggling the can edit to can view.
Please add the feature of user groups to libraries, and vote here if you agree.
