The kanban view is fantastic! The way I'd most like to use it is to manage my pipeline of posts, and in order to do that, it would be really helpful to be able to create a draft post before I have the image. This is because I often plan out my upcoming posts, and even slot them in days, before I have the photos taken (which I like to take in batches, and it would be really helpful to have a column of "needs photos" and a column of "photo taken/needs edited").
Currently, I am using notes to keep track of these post ideas and to attach them to days, but it would really be ideal to be able to create the actual draft post, so that I can slot in the post date and start working on caption and hashtags even before the photo is ready -- then the final step in my process would be to select the image and finalize the scheduled post!
