Feature or improvement you want

It would be a good idea to have a configurable window for what is considered online nodes (default 2hours), now that telemetry is off by default. Perhaps long pressing the "hide offline nodes" toggle would bring up a time slider.

Why should this be added?

Additional listing features now that telemetry is suppressed by default makes sense.

This is managed by the firmware

Then don't use that firmware function. Filter in the app instead.
