Currently, if you use the /em command from a roll button, it displays whichever option you have selected in the "as" dropdown in the chat window. So it would say "<Whoever> rolls [[2d6]]." This complicates things for games where people play multiple characters, or for GMs. You have to remember to change the dropdown before you click the button. I'd like to see the roll buttons from within a character sheet use the name of the character that the roll button belongs to, instead. So if you clicked a button it would output "<Character> rolls [[2d6]]." even if you have "Player" or a different character selected in the chat dropdown. Alternatively, allow sheets to use /emas @{character_name} command for non-GM players.
