I'm having trouble with the auto-save feature.
I have a workflow that uses a lot of memory and can take some time to run. If auto-save is enabled, and KNIME tries to save the workflow while it is running, it locks up and I have to kill KNIME.
Upon reopening KNIME I find that the auto-saved copy of the workflow is empty.
May I suggest an alternative/additional method of workflow recovery: rather than saving at timed intervals could we please save on-execute? This isn't going to be needed all the time, indeed it would be a bit annoying for quick workflows. Perhaps an additional button for "save and execute all" could be added, or control-clicking could save and then execute. I'm not interested in saving data, but I need to be sure that when I run a big workflow I can kill KNIME, reopen it and try again without having to rebuild.
P.S. Nice work on the new database nodes!
