Full and quick control on drawing scale.

I would really appreciate if it was possible to control (i.e.: set up & check the current value) the drawing scale directly from the command bars, without having to get deep into the Options menu (which is really unpractical and slow).

Actually there is a "Drawing scale" icon, but it allows to choose only among a limited selection of values: if the required drawing scale is outside this range (which happens quite often in my job), there is no alternative from the Options way.

Moreover, if the scale is not included into the above-mentioned selection of values, the icon will not show the set scale value, but only a totally useless "Custom" string.

Please, improve this item!!
