Here are some miscellaneous utils for LFS. Actually you should never have to use theme.
LFS provides an aggresive caching strategy for all content like categories and products (dependen on your environment). Actually LFS deletes outdating content automatically. However if you experience old content you can always empty the cache automatically.
LFS manages internal category levels. Here you can create them safely new if something went wrong. Howwever, you should never have to use this.
