Description

Today the "Queries" section of the WebUI shows SQLOperations that are not closed.

Elapsed time is thus a bit confusing, people might take this to mean query runtime, actually it is the time since the operation was opened. The query may be finished, but operation is not closed. Perhaps another timer column is needed showing the runtime of the query to reduce this confusion.
