As a process architect and/or plant layout designer, you have the issue that your resource tree is completely flooded with "Behaviors" and "Publications" objects that you don't need in the use cases you are working on. In order to hide behavior and publication objects from your resource tree, you are now able to uncheck two new options in your preferences. The default is that both will be displayed.

These options exist in Limited Availability (LA) since R2017x FD07 & R2018x FD02. They will be available for everybody starting from R2019x GA.
