Some time ago there was a post about L4 trying to cluster like resources together when they were opened. There are two problems in this area:
1. L4 does not remember where a resource was last opened, but insists in placing it in a location of its own choosing, which is often unrelated to the existing tabs in that location, and ignores much more similar resources elsewhere.
e.g. I want my lexicons to appear in the lower RHS, so I open DBL Heb and drag it from the top left, where it appears initially, down to the bottom right. After closing, and opening DBL Heb again, it reverts to the top left.
2. The "Cluster with Like Resources" thing seems broken too. I open TWOT Heb lexicon in the lower right, and then open DBL, but DBL appears in the top left again.
I haven't tried with other resources, but this is very annoying. Can L4 not at least remember where a resource was last placed?
