Devs,
Unfortunately, I couldn't test this again, but here is the behavior I observed:
1) Turned on comp
2) Indexer fires up saying it has work to do 'preparing my library'
3) Pause the indexer
4) Launch Logos, switch space
5) Go back to space occupied by Logos, app hasn't open stuck on preparing library
6) Unpause indexer
7) app finishes loading
