It would be great if you could have more flexibility with solution writing.
- It would be great if we could edit our solution AFTER publishing, because mistakes happen even if you are very careful. Right now it is annoying to add "EDIT" comments, and makes the solution less readable in case of mistakes.
- It is annoying that once we put the solution "private" you can't undo that. Or the other way around. Maybe you chose one option or the other by mistake. So the ability to change the privacy of the solution would be nice.
- It is even more annoying that we can't write solutions after we read other's solutions. Maybe you come with a much better, clean and simple solution after reading other's solutions, and you want to share it with the world. I've seen a lot of solutions inside the comments because of this, so it isn't very organized. I propose we have the ability to post solutions after reading OR at least have a warning that we will not be able to post new solutions after reading.
