I love the idea of giving instructions with a live document, but you lost me already at this second step:

> "hover the topright of this grid to see the mark button, then click it to mark this grid, then right click the mark sidebar item to edit this grid in the free editor"

I don't see a grid anywhere on the screen. I tried hovering in various top-right corners to figure out where a "mark" button might come up, but to no avail.

I suspect the word "grid" means something else in this application than the usual visual meaning (a regular network of orthogonal lines). You should probably define it first.

Sorry. Cell would be better. Thanks for catching that.
