I can’t imagine anyone finding the selection process of the 4 highlighted models for their own profile successful. Here are the problems I see:
- Re-selection of all 4 models with any changes.
- Selection order determines display order.
- No text search.
Here are my suggestions for improvement:
- Display 4 fields representing the later order. Clicking on a field opens the model selection list. Exactly 1 model can be chosen from the list for the currently active field.
- Text search field that performs live search/filtering in the model selection.
- The 4 fields are sortable via drag and drop, similar to images and files.
