Hey! I can create a post from the mac app. I actually send a stub to the server which creates it, returns a new version of the post, which I then insert into the post list and select. Hit the edit button and there you go. No need for a “create” vs “update” mode in the editor. I don’t know why I didn’t think of this (i.e., see that desktop apps worked this way) decades ago.
Added a delete post function, too.
What about this: the blog platform lets you write a lot of “micro” posts, spots, let’s say, just small paragraphs. You can set each of them to “publish” or “draft”. You bind those spots to a day. Select the day and hit “publish” and all the spots get bound up into a single post. I’m not sure that the binding needs to be a day. A session, perhaps. Or packet. Or moment. Pick a term. Stanza? Write up small thoughts as they occur to you. At the end of the day, or the next morning, put selections in a box and publish them.
