Not exactly a question, more of a "For your information."
I'm not sure if it is supposed to work this way, but here is what I discovered.
When you open Biblical Terms renderings, you see the terms and renderings from the default terms list for that project. This is set in project properties, in the association tab.
If you open a different terms list (in the Biblical terms renderings window menu), then save your layout, restoring your layout will open Biblical terms renderings, and it will be using the non-default terms list you selected when you saved the layout.
This may be useful, it may also be unexpected. My wife was suprised to discover today that her Biblical terms renderings was open to Major Biblical terms, not the project terms list which is the default. But someone might appreciate that saving the layout saves the currently active terms list.
