I really don't like how crippled the WordPress iOS app has become, if you don't use the Jetpack plugin and chain your site to WordPress.com/Automattic.
For example, you can't initiate a new post from the share sheet (say you want to share a link from an RSS app, or something), which is about as basic as it gets! Opening the app from the launcher and starting a new post works, but it's extra friction if you just want to fire off a quick post. There's really no need for it to be like this, and I can't think of any good reason for it.
