I was able to get assistance with adding/removing mime types globally for CoursePress file upload modules which helped immensely.
The feature request that I have is the ability to override the default min/max file sizes, min/max dimensions (for image mime types), and the actual mime type(s) allowed on each individual file upload module.
I am thinking that this would also have a settings page added to globally apply size, dimension, mime type settings that would be set as default on the upload modules. You would also have the possibility to define custom mime types to a list. These mime types would then be selectable from a dropdown in the file upload modules if you choose to override the defaults.
It might also be helpful to allow a custom path so that you can isolate "dangerous files" from web accessible directories. This would be helpful for programming classes when students need to upload .exe .js. py, .php, etc. as fulfillment to their assignments.
