Sub-areas would help organize worksheets
As a circuit designer, nearly every worksheet I create has an initial section with lots of component definitions. Some of the component definitions are fairly lengthy and include discussion. Depending on the design there could be upwards of 50 components to define, and that's before anything remotely useful is done with the worksheet. I usually organize worksheets into areas such that there's a component section, an error analysis section, a spec section, and random other sections as they become necessary. I would love to have the ability to further segment each section/area into subsections, but alas... subsections/sub-areas are not supported (as far as I can tell) in MathCAD in any version.
As a result, I have component sections that are 20 pages long. And every time I want to tweak a component parameter, I have to dig through 20 pages of components to find the one resistor I'm interested in so I can change it's tolerance. It would be much more usable as an organizational/documentation tool if there were more tools to organize and document the math. Sub-areas, on the surface, seems like an easy to implement means of giving us better organizational tools for our worksheets. In the case of my specific components problem, I would have an area for components, and then sub areas for each circuit or each component or each component type or whatever fit my fancy.
I have used references to other MathCAD documents as a means to segregate and provide heirarchy. It works pretty well when I have a big header section like with component definitions, but this is less than ideal in several scenarios where I'd like to just add an sub-area for some note or some side calculation.
Am I alone in this wish? Is everyone else happy with a single level of heirarchy in their MathCAD worksheets?
