I red through the forum about binary star problems.
As this, I think that the "planet-binary stars" are a good temporary solution.
I also think that the major lack at the moment are variable stars, even at a early stage.
Eclipse variabiles, as Algol or Sheliak class binaries, are related to the first problem. So, nothing to add about that.
But, what about phisical variabiles as Mira Ceti, Cepheids, T-Tauri etc?
I wrote in the development forum some suggestions.
