When spells affect your board-state/hand-state/grave/etc, then please check to see if there are any relevant game actions that should prompt for priority.

It is my main phase (as pictured) and I had creatures who could have floated mana but MTGA doesnt have this as a rule. So Cyclonic Rift here doesnt use the stack (essentially).

Of course I dont want hard stops for all spells. I'm looking for common situations to check against (is floating mana relevant? Should the skip button only apply to when my opponent isnt interacting with me/my stuff directly? Should instants and spells with flash keep prompting me when there is nothing to interact with [1]).

When you dont pay for outside help, it is hard to feel motivated to help you to do some basic QA checks.

[1] having an auto ignore option is best!
