I have been a many year user of Documents to Go, way back from the days of Palm, to Windows and now to Android. The latest release gives us "tabs" at the bottom of the screen; pinching to zoom, getting us away from seeming the +- every time the screen is touched, and a few other minor things. The tabs feature for me is not much, really a real estate user. The zoom and no longer +- is nice. However, I have noticed a slower refresh of the screen when a spreadsheet when bunches of columns are displayed. It seems to take a bit longer to display empty cells located to the right of the screen. To deal with this I now "hide" cells to the right and bottom of the sheet and that takes care of the problem; however, hiding via the Excel application within DTG is time consuming, so I do it on the laptop. What would be nice is for Dataviz give us a way to do mass selection via a "select all" option and that is my biggest complaint. Sorry for the boring words.
