I have a problem with the new UI.

After entering the information in the title, description, and tag fields, I do not have the option to save changes.  The save changes button remains grayed out and un-clickable.  Occasionally, after some time, the button will be available to click.  Sometimes I cannot sit here and wait for it to be available.  This especially occurs when there is a problem with one of the data fields.  For example, if I use the same tag twice, it will report an error stating invalid data field.  At that point, I cannot click the save changes button at all, even after fixing the error.

Also, when uploading multiple files, it is impossible to save settings on the videos that have not started uploading.  This means I cannot upload multiple videos overnight while I sleep as they will not retain the information I gave them when fully uploaded.

As far as appearances are concerned, I too believe the text fields are too small.  I have my browser full-screened at a resolution of 1440x900 and they still seem too small.  It takes too much scrolling and I can only see a small portion of my text at one time.  This makes editing the text difficult.

Lastly, I agree there should also be a progress bar.  It should display current upload speed and estimated time remaining at current upload speed.
