This is a very simple thing that could be resolved with going to reading list and do some reread, but in case that @Tony is bored... I want to suggest a confirmation feature, before doing some ticking. Why? 1. I'm sure that I'm not the first, and neither the last person who will tick the check box accidentally 2. Right handed smartphone user will most likely scroll the page from right side of the page, which can result in afore mentioned accidental tick Benefit 1. No losing our reading list tracker 2. No accidental ticking of series we are not reading. Hopefully you also come up with the option to untick the accident...?
