It is a pitty that I have to keep another brand of Bible Software on my computer just for that ability. I won't mention the name brand of that software because this is after all a Logos web site and it wouldn't be ethical to advertise another brand on this site. However this is an ability others have, this isn't something that should be begged for.
The LDLS3 Topic Browser has been replaced by the Factbook and Topic Guide.
An improved version of LDLS3 Fuzzy Search for Bibles is available as Fuzzy Bible Search (in Everything Search in Logos Now): https://community.logos.com/forums/t/132569.aspxWes Crouch commented
I realize fuzzy search is coming "some day" but once again I implore the leaders of Logos Bible Software to bring Fuzzy Search back. It is a wonderful tool that cannot be forgotten and Logos 5 just isn't complete without it.
