Make sure 6.2 Asset app form has exact same fields and configuration as 6.1 form

What is missing

• Language
• Field descriptions
• Tags
• Asset name is a required field
• Media field
  • Label should be "Media"
  • Fix field widths
  • Adjust the title, size, format fields as in 6.1
• When uploading an asset
  • fill "Asset name" field with the file name per default (as before)
  • make sure Media upload field is the same size and aligned with other fields (currently it's smaller and indented)
