Is it possible to add ability to send additional parameters to providers in some way? I think this would be excellent for apps which can select environment depends on some conditions. This is easy to realize by myself but I would be really happy if I would not modify nothing in this excellent code (possibly only configs).
RE: More parameters for connectors
I have database with documents (each with unique ID). It is not good idea to use for all documents one image folder (and even manually created subfolders in it as in current release would be able) because I have hundereds of thousands documents. So for each document I create separate directory and I need it would be root for image browser and other image-related dialogs. Currently I add variable in JS source for document ID and pass it through all required places.
To my mind this is very useful for additional customization on server side to make this change in release.
