What is the proposed idea/solution?

Creating a dedicated workspace for formulas that are on the bottom of the window in a Base that will generate greater visibility for formula expression writing.  It would also be very helpful if the formulas would have more predictive capabilities.  

How does is solve the user problems?

The current floating model is often too condensed to navigate or edit when dealing with lengthy formulas.  This would allow for greater visibility. 

How was this validated?

There can be a "expanding" button that could create either a pop up window or a lower page window for viewing the formula.
