Adapt label value display in map of (unselected + selected) topics and in sidebar
The best solution imho would be to let plugin developers (1) a custom endpoint to fetch a custom DTO and (2) a custom rendering function which can calculate the label displayed based on the custom endpoint response (e.g. aggregating name values of certain childs but not all).
I know this is a seperate issue but maybe this can be solved in conjunction with #45 (closed).
