Why do you have to change it? If you can still open it, just continue, but for more detailed reasons, of course you know why you are asking like that. I think the suggestion from brother @Zaguru12 is a very good reference because it is very clear the stages of work there.

If from me, for other improvements, try to make quality posts and I'm sure if it's good both in terms of concepts, presentation of problems and requests for solutions, I think many of our seniors will give good answers.
