When an user uploads an image via InstantCommons, then you see a Category picker:
Lot of users copy the categories from an already existing file. These categories are in this format:
[[Category:Files from Norwegian Air Shuttle]] [[Category:Files uploaded by Josve05a (misc)|unuseful stuff]] [[Category:Files uploaded by Josve05a (cleanup)|other stuff]] [[Category:Aviation files (check needed)|other unuseful stuff]] [[Category:Files from mynewsdesk.com]]
Then users are tempted to paste this wikitext into the Category picker, but it does not work and they have to manually write each category, one at time.
I would like to paste that wikitext into the Category picker. UploadWizard should convert the wikitext and I don't want to have to add each category individually, and I do not want to "append the blurb of categories" either, I want to be able to paste this in the categories-field.
