🎯 Goals for upcoming releases

As discussed in the Online Developer Meeting (2020-10-27), this wiki section is for a list of possible goals for the next release. Although anyone may edit the wiki, this section is intended for active developers, not a place to dump wishlist items or feature requests. Please create a subsection for your ideas/priorities.
