What is "Click and Drag to Roll Dice"?

EDIT: Solved! Thanks, Gauss. I'm back at Roll20 after having last used it in early spring. On a new Jumpgate campaign I have started, there is a feature I do not understand for both the dice roller and for the character sheet: the Click and Drag to Roll Dice feature. There is a "disable" button thing on it which does not disable anything. It is not there on older non-Jumpgate campaigns. What is the purpose of this feature? Is there any way I can disable it? It is pretty irritating after the 5 years we've been using roll20. Thanks, -- Tim 

Hi Tim M,  Could you provide a screenshot of what you are referencing? Edit: nevermind, I see it. You have enabled 3d dice without checkmarking the automatically roll option. This is not a new option, it has been around for years.  To fix this please go to your My Settings tab (top right corner of the game) then go to Dice Options. There you can checkmark automatically roll.  Regarding why this feature exists, the click and drag impacts how the dice rolls. It gives the user some control over the speed and direction of the die travel. Ie: it "feels" more like rolling dice.
