I am a user of FrameMaker for decades and now the 2019 version. Here are elements that are missing from FrameMaker 2019 and do exist in MS word:
For 1. Bibliography you may have a look at my web site: Bibliogrpahy with Citavi or Endnote.
For 2. Equation Editor you may look at my web site: Modified Equation Palette.Well, it's only 125% of the original size - but it's using fonts. So I could build a larger version also - but not for all FM versions back ...
I have not seen any answer from FrameMaker yet after a year! Pretty amazing.
