FWIW, OOo itself also now has...
      * spellchecker (hunspell backend) and thesaurus
      * email mailmerge feature (pymailmerge)

For Metrically equivalent fonts just...
      * grab the Liberation fonts

For "Macro Migration"...
      * grab the ooo-build vba implementation, which is a superior approach over the StarOffice mess, ships with most distro OOo variants.
