I would like to see the rest of the books of "James R. White" in Logos. While there are the most important already available, some classics like "The Potters Freedom" are missing.
You can support those with a uservoice vote:

And some books already available in Logos do have a second version (e.g. The King James Only Controversy, Updated and Expanded Edition or Sola Scriptura)
