Read/reading indicator

[Bizbif]

Would it be possible to add a visual indicator to the icon to show a book's read status when browsing files: maybe leaving the color as-is for unopened, changing it mid-gray for in-progress, and dark gray or black for finished, or just adding a dot to indicate it's been finished? I've got things divided among a number of folders and subfolders, and I don't always remember where I left off when moving between them.

I very much support the adding of this feature :) sounds very useful
