Question: Can ACT have more than one configuration? (Almost required for multiple game support)
Aside from the Import/Export XML settings features, ACT will load configuration files named after itself.
As in normally it loads %APPDATA%\Advanced Combat Tracker\Config\Advanced Combat Tracker.config.xml.
If you were to rename ACT's executable to ACT.exe, it would instead load %APPDATA%\Advanced Combat Tracker\Config\ACT.config.xml as its configuration file.
If you do this, you should also make a matching Advanced Combat Tracker.exe.config as that file is required for DLL plugins to work correctly.
As there are now two separate ACT executable files, they must also be updated separately. Recent versions of ACT should properly auto-update their own existence.
