Add a "refresh" (or "reload") button to allow for the study list to be fetched from the server on demand
To improve performance, OHIF creates a local cache of study results so that it isn't necessary to send queries to the DICOMweb server. While good for performance the study will fall out of synchronization from the set of resources available on the server.
There is no way to "reload" or refresh the study list for a specific set of parameters without refreshing the whole page, which unsets the active server and navigation position. It would be better if there was a "refresh" button or link in the study list UI that allows for the study to be updated from the server on demand.
