Powercards is an API script that predates Roll20's roll templates. Powercards allows a user (any user, not just the GM, on per-'card' basis) to change anything and everything about how a macro displays its output. Change title, sub-title, and/or body text font, color, background color, formatting, justification Only show information if a dice roll or total meets certain conditions Whisper a roll to someone or someones, even make it so the originating player does not see the messages (perfect for blindrolling so only the GM sees the result) Around v3.4 the maintainer switched from Sky to the new person, and it became a OneClick API Library item, easily installed by any GM in a campaign where the Creator has a Pro level subscription. There's a number of threads about Powercards in the API forum.
