The sheet that Mike posted in this thread serves as a good example:
The solve block is huge, and can't be shrunk beyond a certain point. It consists mostly of white space, and occupies far too much of the page. I can get rid of some of that white space by putting the cursor in the different areas of the solve block and backspacing, but that is a real PITA! If I do do that, then I can't read the labels on the left of the solve block because they are all overlapped. When doing this I have also managed to get the solver section above the constraints section. In Mathcad I could write that, very neatly, on one line, and that' what I would want to do in Prime too.
Also, I don't want to see the border of the box all the time. I would like to be able to make it invisible unless I click on something in the solve block, in which case it shows up. The same goes for program blocks. Can we please get rid of the ugly double line on the right. It serves no purpose whatsoever.
