I have just completed the final version of the "RML Labs Session|Show Development" menu script.
Here is an image of the completed script, along with where that menu is positioned within SAW and SAC.
Of all of the versions that I have been toying with, this version is the least invasive, whilst still being very accessible.
Though the initial launch positioning of the menu is "fixed", the menu is still "movable" and can therefore, be positioned wherever the user prefers.
