I think this area is ripe for improvement. I find the media management experience on the WP app really frustrating:

- There's no "choose from media library"
- If I want to include an image in a post and set it as featured image I have to upload it twice
- There's no "quick image" function, which I'd love.

I know that the app isn't given much love by the community and is mostly an Automattic effort, but it really needs to improve this area.

Pressgram had potential. It's a shame Jon seemed to have got the model slightly wrong. I'd love a separate app that just takes a photo, uploads it to a new post in WP with a title, caption, tags, categories, and sets it as featured image. This would let you use WP as a photo blog. And with the right OpenGraph meta data you could then post to social networks without giving them the image!

I'd also like the "Quick post" dashboard widget to have a "quick photo" mode that works in the same way. And yes, this is on my side project list to create!! :)
