Proposal: Native, customizable window controls tags

[ghost]

Context

In the context of Web Applications, developers need the ability to customize the look and feel of the application such as they are indistinguishable from native applications. This would be possible in the context of a frameless media feature.

Web bundles could thus use a frameless display-mode in order to achieve the desired effect, which could be set into the manifest of the application.

Proposal

In the context of the frameless display-mode, of a Web Application, we could introduce native, CSS customizable and extendable HTML tags for, "minimize", "maximize", "restore" and "close" window controls, which would be part of Open-UI:

<window-close/>
<window-minimize/>
<window-maximize/>
<window-restore/>

Developers could then style the window controls in the corresponding media query.
