It would be a nice feature to implement some basic image editing (crop, etc.) on uploaded assets. Maybe with a library like this:

There are a bunch of feature requests around assets. I will probably handle them together.
Hi, I have implemented it in the current master branch.
Unfortunately the rotation implementation is very useless.
Because rotation is very important I have replaced the image editor with a more lightweight solution that actually works.
