Applying group selection conditions using groupeddataframes

Thanks a lot @kmundnic! process2 is helpful for me because it uses syntax I am familiar with and still improves performance.

Since I am new to groupedddataframes it would be helpful to get a snapshot on the current frontier regarding data selection. Specifically, is there currently an efficient way to

  • use logical indexing on rows of groupedddataframes? (I only found those indexing options.)
  • apply selection functions such as filter on groupedddataframes? (This question seems related.)

Thanks a lot to everyone!
