With the local profiletheme plugin it's possible to link a specific theme to a user with an extra profile field on signing up, based on rules that an admin can create. I've tested this plugin (M3.6), and this works fine. I was wondering if it would be possible to use the same sort of functionality, but then within a child theme of Boost.
E.g. to link specific scss-preset files to specific usergroups with an extra profile field on signing up. Extra themes means many extra files. When you only want to define a set of different colors for specific usergroups, it would be more efficient to look for a solution within the same theme. Would this be possible at all, if yes, what would be a good starting point?
