(Thinking in the context of 2826)
At the moment "Auto-Logout" is pretty much all or nothing. "Auto", "Entirely off" ("Disable Auto logout"), or a range of small values up to 10 minutes (manually selected on each session).

Limiting idle session validity is a great thing, but where physical security can also be taken into consideration, the available values re either too draconian, or useless (the "Disable auto-logout" setting).

So I'd suggest allowing a longer "Auto-Logout" duration for one (or more) trusted IP ranges - maybe 1hr? Maybe selectable? (30m, 1h, 4h). That would be far less annoying for times when you are tweaking a configuration, testing, tweaking again, from a physically secure, low risk location.
