Currently if I change the $filename value in a Export config used by an Action, the change fails to take effect on Action "Export file name" until I e.g. enter the Action definition and change the config selection to another, and then back.
It would be nice if this was remedied.
EDIT: The same problem occurs on the Export config from the File, Export command e.g.
1 Create an Export config having $filename specify a filename e.g. http://i.imgur.com/HfvZxnS.png
2 Close the Export dialog
3 Edit the filename in the config file e.g. http://i.imgur.com/vm40KYi.png
4 Do File, Export and inspect "Export file name:"
Expected: filename changed
Observed: filename unchanged e.g. http://i.imgur.com/wjTd63y.png
