While I was looking at a module one of my players bought me as a gift to fill in the time. I am not an experienced player knowing half the rules or even understanding R20s full features and tricks. I pick up what I remember in the books and more experienced players. As I was looking at the maps and editing some things that needed a few adjustments or reworks. He explained to me people will automatically go through windows because they will think it's a door or not closed. I thought and maybe a lot of people have thought, why couldn't there be an option to have dynamic lighting for windows? My viewpoint is, we have a specific icon to click to windows/glass. People will be able to see through the lines we created but won't be able to enter without making some sort of action. It's an extremely minor thing but I think it's quality of life that could go a long way for Game Masters and create better experiences for our players.
