Looking for advice from other GMs...
I've been using Fantasy Grounds for... a lot of years now... and the thing that continually frustrates me is getting my players to pass their turn in combat.
For YEARS now I've been politely saying "Is that the end of your turn, Sir?" when the player has stopped taking actions.
When I'm teaching players to use FG, I ALWAYS stress the "pass your turn" button at the bottom left corner of the Combat Tracker.
For a while I decided to just do it myself... just click the bubble on the left edge of the combat tracker, but my players get frustrated when I do... "I wasn't done," or "Hey, can I still move my token?" or "can you give me my turn back so I can roll a bonus action?" or something. They cannot, for the life of them, figure out that the combat tracker doesn't lock them out of the map.
Recently I made a big bright red and yellow image that I can share with them that reads "Is that the end of your turn, Sir?" but that really just feels obnoxious.
What do other GMs do? How do you teach your players that one thing you've been telling them for TEN FREAKING YEARS that they just refuse to learn?
My players aren't stupid... they're just... I dunno... stupid?
