Oh, in other words, CC will still be on the read-only mode and, since I'm relying on Cloud library, I will have to keep using Google form (then save as cvs, then import to Calibre when I'm using it) to update read status, comments, etc.

Ah, dear Chaley, I admit I quit using the yes/no column for read status, such binary option is not enough for me. I'm using now a text column with 4 preset values (read, reading, abandoned, planned). I lose the green check in CC but it's easier to keep track of my reading.

One more thing, I've changed system language to Vietnamese and choose "system" in CC language ==> the language interface in CC is stable.
