I think it is amazing and wonderful all that Logos has accomplished since introducing Logos 4. We sometimes take this wonderful program for granted. We use it daily and through familiarity can lose the wonder of what it does for us.
I have been using Logos pretty much from the get go. (At least from the time they bought the rights to the old CDWORD program and offered an upgrade to Logos.) For me it has just gotten better and better over the years.
The recent additions of Personal Books for the desktop version, as well as highlighting and notes for the app are a blessing. Personal Books is something I have long looked forward to having. It allows us to use so much public domain material that may interest a small group, but will never be published for a large market.
In the immediate future, I hope Logos will make access to Personal Books on the iPhone / Android apps a priority. And I look forward to refinements in highlighting and notes, as well as continued improvements in the program.
The Logos team never stops working for us. Thanks!
