Ping on the arr status web is local to the webserver not to the client so not much use anyway (maybe only to indicate some generic issue with a particular server). In regards of AFK - they said they'll look into it after completing the current planned maintenances, not that they'll implement it (for sure). Personally - I think it's waste of the resources to implement such feature as people who intentionally AFK will know how to circumvence the system anyway unless it will be some horrid and annoying solution where you'd need to click couple of confirmation dialog boxes "randomly" placed every few hours to not being automatically logged out which I hope they'll not chose to implement (for obvious reasons).
