Pimcore has a Edit feature with a tiny editor, which probably gets almost no use. However, a Review feature would be very useful. In Google Docs I can select an area of an image and write a note. This of course is how teams collaborate. There are a bunch of html5 scripts that do this annotation.
Of course the metadata generated such as the location of the box, size and text would need to be tied to versions. Notes & Events of Properties (which I do not understand) do not seem to be versioned.
Are there any plans on the roadmap to have an image review tool? Seems way more useful than a tiny image editor.
