Question for you product development lead... Did you bother to interview or ask questions of anyone actually using this program? I HAD BEEN praising whiteboard left and right. I'm a consultant and HAD BEEN using it constantly internally and with clients. THEN, of course, you went off and made it far worse.
#1 - We can no longer copy and paste into the Whiteboard. This was perhaps its most powerful feature because one could take a screen shot of something and immediately start "working on it." Now, if one wants to do that they have to take the screen shot, put it in some other program, save it as an image, then import it. I USED to be able to take a screen shot and begin making notes against it in real time. Its impossible to do this now because of the time it takes to get the image into Whiteboard.
#2 - You killed its use as a creative drawing tool. My kids used to love to use theirs for drawing. But, you let's see, got ride of the ruler (which was fantastic) and made the pen tool bar far worse. One used to be able to set it up with quite a few colors and pens so that you could quickly create. Now, SOOOO much worse. Its harder to change colors. Its harder to change the size. The click/menu option for changing the pen settings performs far worse than how the previous version did.
There is definitely some good with the ability to include templates (though the ones in there aren't overly useful) and some of the other features; however, you've done more harm than good. Why would you take away some of the best features of the tool just to swap it out for others. First day as a product manager? Not bothering to actually get real user feedback? Perhaps this finds its way to someone in MS' prod dev team at a higher level who can help you (MS PD person) do your job a bit more competently.
