I'm not sure if others encountered this problem (most should), but italics, bold, and similar formatting can't be copy pasted from Gdocs or Word. For someone like me who uses a lot of italics, I find more than a hassle to manually edit the chapter once again.
Rich text formatting software like Word is generally bad for copy+pasting into other word processors. You usually can't copy and paste rich text from one processor to another unless they happen to use the exact same formatting. If you want to copy formatting, take a look at this guide on Markdown. You'll need to disable the rich text editor in Settings.
I'm not sure if there are plugins for WYSIWYG editors to recognize the kind of content from the information the clipboard provides or if the browser even provides all that information. If that's possible, it might be a nice addition for the future. Some word processors allow you to convert the content into Markdown syntax. Personally, I actually prefer directly writing the Markdown syntax as I don't have to use shortcuts or the mouse to format the content.
