Is this a good idea

I have been thinking of an idea where there should be a tag for games without a save feature.
Is this a good idea?

Honestly I completely agree. Games on here aren't perfect and neither are people's browsers. It's extremely annoying to play for two or more hours, have the browser randomly reload, and all your progress is gone. I understand games that run on scratch since while some games do have saving it's a seperate method and it's easier to assume "Oh it's made in scratch so no saving I guess." With those games it's good because you expect there to be no saving and then it's a pleasant surprise when there is. But with other games especially ones where you know it'll take a long time and you go to take a break, only to come back to find all of your progress lost. Sorry for ranting so much, but I agree with you.
