Just my early impressions but here goes for (hopefully useful) feedback.
I wish there was a way to check the list without turning on your own lfrp. There are a lot of times where I'm finishing up something and about to decide where to go next without wanting to say "hey, I'm over here, come here for RP" when I'm about to leave that place.
Anonymity options would be nice. Not knowing who you're going to run into to would encourage meeting new characters. Also, some people might not want to broadcast where they hang out. (less important for my current main, but still)
It's also nice to know where RP is happening sometimes, so an option to turn on/off a passive, persistent, anonymous marker of "X active players are at Y location" would be nice, and I think would get more use with how many secretive characters there are.
Alternatively, just have certain hub areas just keep a count (perhaps obscured by delay &/or fuzzy logic or something). Examples of such locations in Barovia would be Western ouskirts, ML temple, the inn (though probably not the upstairs), and the drain.
It's a bit of a letdown to make a bit of a trek to the outskirts or the mist camp only to find the place deserted, as I expect -many- people know, but the current system wouldn't let you know that as {everyone in rp}={0 lfrp}={empty area}
Could even have large enough groups that are both semi stationary (aka not just resting/passing through) and not in a dungeon trigger to be temporary hubs to help facilitate player run events. (though that last one would have some downsides, admittedly, but could be offset with a "hide" option of some sort).
