Please can you send me your account Id.

This will be vastly improved very very soon. I didn't have enough time to add individual selection.

You can create fake articles in the Browser account.

Unfortunately, this is not possible.

The image editor has gone. It was very old, clunky and most of all the plugin was deprecated years ago and recently caused a LOT of crashes. So for the time being, you can only crop images. There are plans to try to replace this or find something similar, but the first priority is adding support for multiple images.

I plan to add this in some point soon.

You already can. Follow the tutorials in-app.

Not anytime soon. The way it works at the moment refers to where users are placed. So if you move them around, posts with assigned users change too so it would be very confusing.

Perhaps somewhen in the future.
