Topic on Talk:OOUI

Can someone please explain to me why OOUI impacts all skins and has not been developed as a skin on its own. It would allows users to use the old beautiful "Vector" skin without all the ugly (on my opinon) changes made by OOUI. It makes using Wikipedia on a computer not very practical (widgets like text input, check boxes, radio buttons too big, too much spaces between elements...).

• So why OOUI has not been developed as a separate skin ?

• How to disable OOUI and revert back to legacy Vector skin ?

The OOUI library is not a skin, it's an interface toolkit designed to be the interface for all of MediaWiki. The equivalent question is why Firefox has been developed as a browser and not a website.
