• The first problem is fixed by !1320 (merged) .

Instead, the associations are only changed when a user double-clicks on the operation in the list of available operations.

Now the associations are shown explicitly as part of the operator's parameters and can be updated with the copy from selection button. Please close the issue if this is sufficient.
