In relation to Condition: "no/any internet connection" you recently added for 1.8.0 to address this issue.

One tiny nitpick... When "internet connection" condition is selected, there's a choice between "not in use"* & "no internet connection", that's clear enough, however; when one selects "no internet connection" the description underneath says "when no internet connection is in use", that's a bit confusing, it would be clearer if it said "when internet connection is disabled or unavailable".

Great little condition either way, I've created a rule where-by; "If there's no net connection (or it's disabled) -> set availability to offline for all chat/msg etc services".

*The description for "not in use" is "not in use", perhaps that could be more explanatory too.
