Upload and ajust images like Blogger dashboard
I think that the posting dashboard of blogspot.com is really cool and usefull and provides a great control about layout of images, and this resources on the app can be the great upgrade on the app.
The more the app become similar to the dashboard, more easily it will turn the substitute of the blogger native posting panel.
i only can link a image
Uploading images to Blogger's default image server would be logical, instead of having to upload via another site, then entering a URL into Hootsuite's post composer, manually!
(Even better: support Blogger.com as a full social network!)
Another thing I forgot to mention is a system to save posts, so we can make a revision and later, after this, post the final text.
