What skins are visible or usable by other players?
Skins purchased in the shop (see what can I find in the shop) are only usable by the person who has them on their Let's Role! account, but some are visible to other participants.
Everyone can see your dice, but only you can throw them. You can (for now) only use one set of dice at a time.
Everyone sees your avatar frame in the left column and your token frame on the virtual table. Only you and your GM see your avatar frame on your character sheet.
Only you and your GM see your sheet skin.
Only you see your table skin, but everyone else sees the GM's table skin if the GM shares it.
Only you see your icons.
