I will preface this by saying that I did a search first before I asked this question, but so far, by the way I framed my query I could not find an answer. I don't mean to rehash.
I have a few Visual Markup, Filter, and Layout files that were developed by Calvin Seminary for Logos 3. They end with these file extensions: .lbxvmp, .lbxvis, .lbxctb. Can they be used in Logos 4 Mac either now or in later versions?
