But I may not have understood your question properly. The num_alt_modes property - can the number be perhaps aquired from the number of created directories? Or would that number of alt modes be created automatically (all same with default values), and the properties in alt.X dirs would subsequently only modify their respective values? > > And second, should the alt.x directories go back to the defaults if you remove > and re-create them?

IIUC just creating the alt.X directory would create the alt X mode, with default properties from the top-level configs or with the source-code defaults. Thanks a lot, Pavel.
