Switching the original language
The Add-In always considers one language to be the original language of the project. You specify this when you add Multi-Language support to the project.
Up to now, there has been no (official) way to change this attribute.
Actually, I have wanted to change the original language of a project quite often, but have always figured that normal users would not need this feature. (I was able to do it by editing the project database directly anyway.)
Now I have finally added a command to the context menu on language columns to specify that the selected language is the original language of the project. This is available in version 4.65.0061 of the Add-In.
By the way, my motivation for this feature was to fix a problem in C++/MFC projects. The Add-In only scans the Dialog and Menu resources which are defined for the original language. In this case, if the wrong language is specified, the Add-In does not detect the Dialogs and Menus at all!
