We gray out buttons when deleting a client and provide a spinner if it takes a while but when deleting a really large client, such as when harvesting all of IQSS, there is not much feedback as to progress or how long it may take. Additionally, if you refresh the page or move away and come back, the grayed out status and spinner disappears and it is not clear how or when it may finish. Also, not much info in server log on status so can't see how far along it is.

Update: it appears that refreshing the page halts the delete in progress.
