It’s OK; very simple, but could be better

Very simple. I don’t like that only square photos are possible (other Instagram uploader desktop apps allow the option of uncropped photos). Would also like to be able to tag other users in photos, expand the caption field (so you can see the whole caption that you’re typing), and have the app suggest hashtags and other users on the fly as you type them, like the mobile app does. It’s a good app for really basic posting but not for really serious Instagram users.
