Simplify login screen

Today the login is composed by:

• a header (hideable) with a background (not customizable), a logo (customizable) and links (not customizable)
• a main content with the login box (customizable) and a news feed (not customizable)
• a footer (hideable) with copyright links (not customizable) and platform version (not customizable)

In Studio a user can:

• chose a background image and make it cover all the screen
• chose a background color
• remove header, news and footer (that are not customizable)
• customize the login box (background + width)

and cannot:

• update the css
• chose a specific logo: the logo used in platform pages is taken and glued on top left
• customize links and news

About the newsblock: missing target"_blank" since a month and a half: I'm wondering if we have analytics on it to see if it's used.

About links in header: Usually you don't want users to get out of your product before trying it. Do we have analytics on them to see if it's used ? I'm for removing them and keep/add them in the footer of the platform pages.

About the header: as it adds more complexity than simplicity, we could remove it (a header is not mandatory and not a need for everyone) and let users add the background image they want (with a small logo in it, a giant, a header or not, etc ...).
