It would be nice if there was a generic Visual Studio exporter that either picked the VS version from a global property or a version dropdown in the exporter.
That way when a new VS version comes out I’d just need to change the property.
Otherwise a command line option to upgrade the VS version. In the past I just edited the .jucer file manually, but sometimes things change between VS versions and I silently broke some of my projects.
When you have 20+ plugins, editing manually is time consuming and error prone.
