The WME Mobile Support userscript makes various changes to the way the WME gets displayed in order to get it somewhat working on a mobile device.
Please note that Google Chrome for mobile devices does not support extensions. Firefox mobile however does and TamperMonkey can be installed on it.
Please note that the intention of this script at the moment is not to provide the full editing experience you get on a desktop, but just tries to enable you to handle various actions requested by people who supplied a permalink while you are mobile. The script is also still under heavy development.
