A dummy interface?

Ok, this is a bit of an odd question, so I couldn't really think of a more appropriate title. Anyways what I want to do is this: In my map, I want to make it so that there's a "global" interface for managing certain things. Right now, all I have planned for it is setting tax rates and gathering general information about your city, but I can think of many other useful things for it. The most user friendly way I can think to do this is to have a dummy unit with an interface dedicated to the various commands. Those commands would of course be tied to appropriate triggers. That would be a lot easier and less disruptive than a clunky dialogue menu. Anyway, that bit seems easy enough to do, what I need is a convenient way to select it. I want this unit to always be just a click away, regardless of where you are on the map. My first thought was to make it a hero, that way the hero icon on the left side fo the screen could be used. Unfortunately, I don't want to take that screen space away from other heroes, and the hero stats appearing at the bottom of the screen would be unaesthetic. So, can anyone suggest a way to get a similar icon on the screen? Or how bout another method for easily selecting a dummy unit? I want to avoid a keystroke, too, as I want to keep key memorization to an absolute minimum. Thanks in advance.

A worker? That or a hero is your best bet. Otherwise you'll need to use a keystroke or an ability/item tied to a trigger which every unit has...

So, is it possible to superimpose a new interface button? Also, is it possible to place text over the bottom interface? Could I, put some text where a unit's damage and armor are supposed to be?

Use one of the arrow keys.

I believe that a trackable object might do what you want, but that involves heavy JASS. Here is a link to a thread about it:
