hello Monday! Today we refactored the writing experience on flycat.club, now you can save local draft posts when blogging on flycat.

We also adjusted the layout of the editor page so you get less distracted in writing.

some meta datas will be displaying and required you filling only when you try publishing the post.

you can find your drafts on myBlog page (https://flycat.club/blog/ and continue editing it until you are comfortable to publish it.

As always, we appreciate your feedback. Please don't hesitate to tell me what you think about the updates~
