I have a folder with .XML files and an .AAT file. Whenever I make significant changes, maybe to keyboard shortcuts or layer sets, I just send these immediately, using "export" (in the case of schedules, work environment, or favorites) or Attribute Manager. So this folder always has the latest and greatest. Then, on a regular basis, just import all these into your template plan, which will then also have your latest and greatest. That way, you don't have to keep a separate template file open at all times.
Also, when the next version comes out, you can choose to overwrite or append to a clean new version. Generally, just importing old shortcuts into the work environment does everything I need there, with some minor adjustments to other things that are pretty fast, and I'm good to go with the new Work Environment.
