I was watching you work on 5.0, and I'd like to suggest a couple of tips to you.
Please remember to use edit summaries when you save changes, as it helps the rest of us know what you're trying to do, and why. For example, I don't know why you made the reflist one column instead of two.
Using the Show preview function might help you, as you appear to have made a series of ten edits, most of which you undid yourself. With preview, you can try out your edits and see how you like them before saving.
I hope you find these tips useful. Wishing you a good day. —
