I appreciate the input.
The app was designed so as to show a yea or a nay, but the abstention issue was built in for the lobby so they can understand who has voted or not. Of course here in the chamber if a member wants to abstain from something, they just do not show up or do not rise when the time comes.
The official record does not distinguish between whether a member voted in the chamber or via the app. If members are saying that we should actually underline that, then I would suggest they bring it back to PROC, which can make that determination when the time comes.
