@Holo Although I do have other objections, at least for now it seems to be very wacky. For example, on:
https://mangadex.org/title/12988/hakuba-no-oujisama
it shows:
> Reading progress: Volume 0/10 Chapter 17/112
These numbers, which I had no hand in choosing, are not an accurate representation of the volumes or chapters of this series that I have read. This is just one example, and there many others.
I realize that "vol" auto-update isn't properly functioning (or not at all), as all the series I've checked still have "0" for a volume. But the chapter auto-update is either very accurate with some series or wildly inaccurate with others. For one series, it claims I've read all 176 chapters whereas, in reality, I've only read 7, chapters 0, 0.5 - 4 and chapter 69. On the other hand, for another series, the tracker shows that I have read "0" chapters, whereas I've actually read all 157 chapters.
I also realize that this might just be kinks in the system that would be ironed out over time, but, to honest, I would prefer that "option to turn off the progress tracker entirely," including its display.
