How do you plan to support links between documents. The place I work at now has a very complex budgeting process where each department sends my office their budget spreadsheets and we link them all into an overview that also does things like calculating benefits payments and taxes. There's a lot that can go wrong in that process, and every time I go back and look at a submitted version I find some mistake someone missed.
Slate will show the cells that are in another document but referenced by the current sheet. However, it would not show any further levels of referenced cells.
So say I reference the value "Total Sales" which is in another sheet. That would show in the the tree but the individual sales that contribute to the total would not be shown.
We wanted people to know where the numbers are coming from but at the same time keep the trees for different sheets and files separate to prevent them becoming too unwieldy and hard to understand.
