The KOReader Status bar has the following options now:

Show all at once
Auto refresh time
Progress bar
Chapter markers
Battery status
Current time
Current page
Pages left in this chapter
Progress percentage
Book time to read
Chapter time to read

There are no KOReader-epubs so it works for all the book formats read using the Coolreader 3 Engine (cr3) [That's a lot], not just a proprietary format that only works for books purchased at their store.

There is also a "Book status" menu option, that brings up a full page status display that includes:
The Book cover image.
The title, author, a progress bar, and the percentage Completed.
A Five Star ratting, with the stars filled in, if you have ratted the book.
A "Statistics" box with: Days, Time, and Read pages.
A "Review" area with a good sized box where you can add your own notes/comments.
An "Update Status" area with Complete, Reading, Abandoned - the current status will be highlighted.

Luck;
Ken
