Add file uploads window a'la file download window in Mozilla Firefox.
If in any window somebody starts upload of the file, then Flash connects via Local Connection (Flash therm similar to DDE in MS Windows) with upload window and sends which file to upload to that window.
Research if Flash could programatically invoke file upload without checking it in file browse function. If not, then this idea is not executable.
If file upload finishes, then we should add file info and it should be added in file
upload window.
Window, which invokes upload could be informed, that file is uploaded and some comments should be added (info or even form (duplicate form from upload window).
File upload window could show total upload progress bar.
