UGH BRO I KEEP FORGETING WHAT CHAPTER IM ON AND KEEP LOSING JT😭

What I do is on the 'edit' window, in the 'comments' section, I write what chapter I'm on and check the 'visible only to me' option. I also mark it on mangaupdates.

Sorry, I forgot to add that the 'edit' window appears when you click on 'want to read, now reading or already read'; or rate it. After that, the 'edit' option always appears.
