Hello!
As authors from fanfiction.net, we want to import our fanfiction to webnovel. However, I noticed in inkstone there are NO options for bold, italics and linebreaks which feature prominently in the story as literary devices to denote things like thoughts, flashbacks, and scene breaks. How does inkstones import process deal with these? On another note, its odd that a website for authors to publish in English does not have basic bold/italic/underline/linebreak formatting functionality.
Import from fanfiction.net
Hello, author from FFnet here as well! 
And yes, that's one of the things that Webnovel seems to be lacking. PM options is also one of it too. Because of the lack of options in writing, my readers became a confused at my writing style, especially when it comes to chapters with flashbacks...

These don't exist. You need to reformat with symbols.
I recommend you reformat using Markdown syntex. For the fact that it's familiar to peeps since we use it here.
Any bells and whistles that you might get at fanfic.net and places like Wattpad, like image/HTML embedding aren't here. We almost had it all to be like WP, but it was a no go in the end.
. Too much strain for this platform I think.
