Sell these files through VirtueMart

Hello. A few suggestions:
1) Add the ability to set the theme, sorting and sorting order by default for all categories.
2) Add search and sort categories in the admin panel.
3) When the category name has been pasted from the clipboard, the component should clear the formatting.
4) It would be nice to be able to store files on some kind of cloud storage and sell these files through VirtueMart.
