There are also buttons for cut, copy, paste, and cell color and text color buttons.  I wish the buttons were configurable, however.  The Workbook Details button (to the right of Done) isn't something I need to use often, so I would rather be able to change it to Format.  That way I don't have to use Cell | Format to change formatting.  I also don't think that Delete Workbook (second icon from left) should be so easy to get to.

Speaking of formatting text, there is a host of options for cell formatting.  In addition to allowing multiple fonts (when will a DOC editor do this?) and colors, you can also change the text alignment (horizontal, vertical, wrap).  You can format numbers as general, number, currency, percent, date, or time; border and cell protection are also options.  The only thing missing is a format painter.  I constantly use that in Microsoft Excel, and it would be nice to be able to copy one cell's formatting to another.

There are a few features that I wish TinySheet had.  A full screen mode with smaller row & column headings only would be nice.  If TinySheet used the command-stroke toolbar in Palm OS 3.5 and had its major icons there, I would probably use a full-screen mode exclusively.

Technical Support for TinySheet is very responsive.  I found a bug in the SUM function if TinySheet was adding empty cells, and iambic support had a corrected version done within the day.
