Implementing diagramming in a browser was sure no easy task. There were numerous cross platform gotchas that made it a much larger task than initially anticipated, but alas it is live and functional!

You can create rectangles, ellipses, triangles, lines and more.

Once you've inserted an autoshape you can change it's fill color, line color, line width and line style and if it's a line you can even change it's begin and end styles. Pretty cool, huh? Okay, so what are you waiting for? Check it out already!

We began working on implementing the undo / redo mechanism almost two months ago and now it's finally ready! Unfortunately, it turned out to be a pretty monstrous undertaking as it required reworking complex functionality located throughout the code base. I really hadn't anticipated that it would take a long as it did, but man am I glad it's done.

To undo or redo an action you can select the menu items Edit->Undo... and Edit->Redo..., or you can click on the corresponding toolbar icons, or you can just type Ctrl-X for undo and Ctrl-Y for redo.

If you like to spice up your slide shows with a little movement then check out the new Slide Transitions feature. Not only can you make your slides wipe, push and fade, but you can also set your slides to advance automatically after a specified amount of time.

As you can see, the Slide Transition dialog box is pretty simple, so you should up and transitioning in a matter of seconds.

Here's a not so short list of the currently available transitions:

• Box In
• Box Out
• Cover Down
• Cover Left
• Cover Right
• Cover Up
• Cover Left-Down
• Cover Left-Up
• Cover Right-Down
• Cover Right-Up
• Cut
• Cut Through Black
• Fade Smoothly
• Fade Through Black
• Push Down
• Push Left
• Push Right
• Push Up
• Push Left-Down
• Push Left-Up
• Push Right-Down
• Push Right-Up
• Random
• Split Horizontal In
• Split Horizontal Out
• Split Vertical In
• Split Vertical Out
• Uncover Down
• Uncover Left
• Uncover Right
• Uncover Up
• Uncover Left-Down
• Uncover Left-Up
• Uncover Right-Down
• Uncover Right-Up
• Wipe Down
• Wipe Left
• Wipe Right
• Wipe Up
• Wipe Left-Down
• Wipe Left-Up
• Wipe Right-Down
• Wipe Right-Up

I may get around to implementing some additional transitions on down the road, but I'm hoping that the current selection will prove sufficient for most users.

I just updated the production server with a handful of bug fixes. Following is a list of the five most important changes:

• Saving presentations is now much more reliable (this was a big one!)
• The broken menu items View->SlideShow and Slide Show->View Show have been fixed
• Switching between slides has been optimized and is now much faster when there is a lot of text
• Several problems that caused text not to wrap correctly have been solved
• Check mark menu items are now displayed correctly in IE

There are still quite a few bug fixes on my to-do list, but I'm knocking them out at a fairly good clip, so you should see a noticeable improvement in both stability and performance over the next few weeks.

Yet another interesting use of the presentation format.
