Please add a simple possibility to set the size of an image.
A very basic version is sufficient. Without this feature Dropbox Paper disqualifies for a lot of use cases.
Simple version:
Popup that allows to select a percentage of the original size (100, 90, 80, 70, ... %).
It would be sufficient to simply resize the image in the browser (display size) without actually modifying the data size.
More advanced version:
Allow to input with and height as HTML/CSS values px, pt, em, %.
But I think the simple version is sufficient for 99%.
Additionally there could be a resize via mouse drag at the image corners later.
But in my opinion the basic version would be fully sufficient and may even have advantages e.g. on mobile.
