The relation between sys_category and records is sortable, as sys_category_record_mm contains fields called sorting

However at the moment it is impossible to influence the sorting of chosen categories in when using the field type category.

When there are large amounts of categories in hierarchical structures they are also hard to choose from a list or with the record chooser using group or select fields.

The category tree already has one view where only the checked categories are shown. Now if we could use that field to change the categories sorting that would be perfect.

We often have use cases, where we only display the first / most important category or where we want to influence the sorting of the listed categories. This cannot be achieved with the category tree right now.
