It is not implemented in current version.
Thanks for a quick response. This is a feature I would use a lot, particularly for repetitive setting up of groups of tabs eg for projects, client papers etc. so I am very keen to see if you are willing to add it to the list of future developments.
I notice that DC already saves this information on closing (in the doublecmd.ini file) and recalls it on re-start, so most of the mechanisms to make this happen appear to be in place. Would you be willing to implement it when you can fit it in please?
