HCIM/HCGIM have a rough time on this game with frequent alleged DDOS attacks, and overall frequency of game instability and bugs compared to OSRS. Things like this that don't hurt the game integrity should be implemented.
To anyone commenting similar (but perhaps not identical) plugins exist on OSRS like this one https://runelite.net...party-heartbeat. Party Heartbeat goes a step further and even reports this info to your HCGIM team so teammates can save you if needed.
Regardless what's being asked is a simple timer and overlay, both of which exist in other plugins and the code would be quick and easy to repurpose for this use.
