Yes please!
I know replacing an image might seem weird or unwanted behaviour, but it is very common to use online services as a live repository, and have an app that maintains this state, synchronizing things like comments, keywords and so on. This means we can do neat things like republish export images as we tweak them, or change select metadata.
So, this might also affect your policy of not updating (for example) EXIF data on replace. But I'd be satisfied if I could map the EXIF/IPTC Caption to the title of the image, and /maybe/ sync keywords. Though my app can't do the latter, yet.
Ideally, I want to be able to let you manage Collections and Albums via the app, as well.
My app won't grab existing photos hosted on 23 and manage them. It will provide a "publish service" to Lightroom for drag and drop and push-button publish to a 23 account it gets permissions to via the web page authentication.
Oh, and by the way, I borrowed the little "23" image from the 23 blog and used that to brand my app in the Lightroom UI. I assume this is considered fair use? Is there official brand collateral I should be using?
