(Sorry if this suggestion already listed? The only previous one I could find was 4 years old.) There's a standard playing card deck, but there is a need for safety tools such as safety cards (X, N, O) for example, to be available in every game room also. Ideally these would always be available to the player - permanently selected - but the player could choose to hide them if they chose. 3-4 cards, say a card back and the three cards could be provided, large enough that they can be dropped on the VTT or "played" as cards. The advantage this offers is that they can be played anonymously if desired and can also be played irrespective of the source(s) of the objectionable material. (i.e. it doesn't matter if it's another player or the GM). Making such tools an automatic inclusion sends a strong message about everyone feeling safe and included and free to accept, warn or opt out of material which makes them uncomfortable. It's a good thing to have there if a GM or player needs it, and having visible reminders to be excellent to one another is never a bad thing. GMs have enough to remember, so a reminder for the table is an opportunity to have a conversation or at least check in with everyone that they understand what safety tools are for and how to use them and what other options (e.g /w) might be available. There are lots of card graphics out there, I've been playing around with inserting these into the games in our local group as concept demonstrator. They could definitely be improved. It would be nice to see a visible message that Roll20 and its community care about player safety and hope they comprise a tool that's rarely used but readily accessible when needed.
