I think as the new Moodle 2.0 File Picker (FP) "tools" get broader exposure it would be good for development staff to review recent Moodle lounge thread ( http://moodle.org/mod/forum/discuss.php?d=169791 ) with an open mind. There are very real issues (and solutions) pointed out here that are not "going away".
Two distinct existing sets of Moodle user groups are evident, one group compatible with FP 2.x "style" and one explicitly NOT satisfied with loss of 90% of its file management power tools.
Martin you are on public record as saying Moodle probably can't/won't be a real "file repository" so if the FP 2.x is stuck being what it is currently (I certainly HOPE not!!) then giving an explicit, simpler path/method to get real Moodle file repository (like Alfresco Comm. Ed.) running is something the Moodle community of experienced users deserves.
