I agree, saving the jobfile is a helpful option, and I of cource always use this option when needed.
I am not sure that it is correct to call in an undo-stack, what I am thinking about.
On the page “Select Table(s)” the first column can be ticked if you want to include the table.
1) Try including a table by setting a tick.
2) Then change various settings in “Map”, “Advanced” and “WHERE”.
3) Now remove the tick.
4) And finally set the tick back.
All the settings that you did in 2) have dissappeared.
I would like it, if it remembered the settings.
