This might already have been raised.
Some or our sites have user submitted Custom Module items (1000+ submission / year). The problem we are facing is that users often upload large images (dimensions and file size). In BC we had the functionality in file manger to change the dimensions which also reduces the file size.
Would be even better if such an image processor also would work within the custom module item update form in the admin console.
Are there any plans to add such functionality?
