Don't split up books in "All" view on user's "My Books" page

Description of your request:

Currently, when displaying “All” books, the books are split up into “Reading”, “Finished” and so on. This was very confusing to me this morning because I switched from “Owned” to “All” but did not see my “Owned” books in the resulting list :scream: It took me about 10 minutes and half a bug report to realize that the first list in “All” view is “Reading” :woman_facepalming:

Therefore, I think it would be great to really see all books (in one list) when asking for “All” books…

It would be helpful to have a little marker indicating which group they belong to, though. (which would be visible in “All” view only)
