Since release 1.4.0, Orthanc comes with a so-called “jobs engine” that will display the progress of C-MOVE SCU (i.e. retrieve) in the “Jobs” panel of Orthanc Explorer (under the job type named "DicomMoveScu").

This “Jobs” panel uses the following part of the REST API of Orthanc to monitor the progress of the jobs: https://book.orthanc-server.com/users/advanced-rest.html#monitoring-jobs

As a consequence, a more user-friendly Web user interface could easily be designed on the top of the REST API of Orthanc: https://book.orthanc-server.com/faq/improving-interface.html

This issue can thus be considered as solved.
