One of the nice things I decided to implement for CRUCS was an extension to Typica's XML format. Typica ignores elements that it doesn't expect which means I can put in a <crucs> section with everything needed to exactly reconstruct the editor state. I can add support for that to a future Typica release to speed up load times slightly while older versions will just ignore the new data and fall back on the precalculated values still present in the data file.
