Better file upload

[Deele]

Currently, file upload is very tedious, requires many, seemingly useless clicks to upload and confirm and return etc.

To upgrade user experience, I would like to suggest couple improvements:

• File upload section should be redesigned so that it is more like overlay over file manager box, than "another page" which is confusing users.
• Process of upload should take less clicks - when files are uploaded, user should be taken back to file manager view automatically.
• Selection and loading icons should be chosen less intrusive, they are too big and gives less formal look of module.
