Thanks for coming back here in the Community, @I-Already-Had-A-Username.
Currently, logging people out of QuickBooks Desktop after being idle is unavailable. I can see that having this feature can help your business needs. I'll make sure to take note of this idea.
In the meantime, I'd suggest visiting our QuickBooks Blog regularly. This way, you'll be updated with the latest news and updates, including product improvements.
I'd add an article that you might use in the future about managing your QuickBooks account.
Please feel free to get me in the loop if you have any more questions about your QuickBooks account. It's my pleasure to help. Take care!
