Data import: freeze-like pause after importing importer worksheet (drag-n-drop)
When I add an importer mapping worksheet by drag-and-dropping it into the area in the "Importer List" page, it shows the progress bar going to 100% - and then stops.
The browser doesn't indicate that it's still doing/loading/waiting - and then suddenly (after like 3-5 seconds) the page refreshes and the imported worksheet appears in the list without problems.
What is causing this strange "pause" and would it be possible to give some clue that CA is still busy doing something? Me and my colleagues have pulled our hairs reverting and refreshing, not knowing what went wrong - until we accidentally just waited to see it was still active.
Oh, and it seems that it's not possible to import more than 1 worksheet at a time that way, although the text says "drag importer worksheets" (<-plural). Should it be possible to support drag-n-dropping more than one in one step?
Thanks in advance! :D
