Since some versions ago Google Chrome has introduced a new interesting feature called "Add to Homescreen", which allows to add an app shortcut icon added to a device's homescreen/desktop for any web resource (website or webapp). The coolest thing is that the browser window launches in real full-screen ("app mode"), working exactly like you would expect from a normal web application / native app. This is great when using RuneAudio UI (RuneUI), and works great on PC but even better on mobile devices, where screen space is precious.

(these are the official instructions for Android devices but they are also valid for the PC browser version)
