I gave it a quick spin and it seems like it needs more work to behave like a spreadsheet. Even simple circular references are not detected right now. For example, I put some numbers from A1 through A5 and then put a SUM(A1:A6) into A6. It added everything up (including the sum itself) and keeps updating A6 with the sum of A1:A5 every time I move from one cell to another using Enter or Tab. You can see this at https://ethersheet.org/s/IsThisAwesomeNow https://ethersheet.org/s/IsThisAwesomeNow And also, as @binarymax stated, arrow keys to navigate (along with F2 to edit a cell instead of the default of putting a cell in edit mode), usage of arrow keys within formulas to get cell references (instead of typing the cell reference), easy ways to format cells, easy way to extend the width or height of columns/rows...I presume there's a large backlog of features to implement. :) Right now, this is far behind EtherCalc in terms of features and usability.
