Error message on the WD dashboard

When an error occurs during running of a pipeline, the "Problems" widget appears on the Workflow Designer dashboard. Currently it is not possible to copy the error messages. The messages are often truncated, so the only possible way to see a full message is to hover the message with mouse and read the hint. It is not handy, especially when the message contains a file path that you would like to open. You should at least provide a way to copy the full message, for example you may add a context menu with the "Copy" item.
