There have been a lot of posts complaining about the indexing, and Logos has been known as the slowest software for a long time. Since I order free Vyrso books almost every day, almost every time I open Logos, I have to restart and reindex. Sometimes I just want to look up something quick, but I can't. It's gotten so bad, that often times it's quicker to just open Biblia.com to open the resource I need!
So here's my suggestion: have a program option to open Logos in "bare-bones" mode.
It would be like "Safe-Mode" for Windows operating systems -- only essential applications will run. You would get to choose a select few of your resources that you would want to have in "bare-bones" mode. This would probably include your primary Bibles, a Greek and Hebrew text, and a few dictionaries and lexicons. Maybe a few commentaries. Whatever you use most.
This would mean:
1) No checking for and installing updates
2) No indexing
3) Can only search and access a select few resources
My guess is that would speed up Logos immensely for those times you wanted to do something simple. I would use this all the time!
Theoretically, you could do #3 by hiding all of your resources except the ones you wanted in bare-bones mode, but then you'd have to unhide everything again when you want to run Logos normally. I think having two different modes would be fantastic.
