In the last few days, I have made some releases with a couple of bugs. These have all been cleared up.
The Dungeon Master's Cheat Sheet is an HTML file that can be edited right in your web browser, saved and reopened later. It is made to be a place where DMs can store all of the information about PCs, NPCs and Monsters as well as information that pertains to the adventuring party as a whole.
It is now in version 0.3 as it makes its SourceForge.net debut. It is in a playable state and works well in both Microsoft Internet Explorer and Mozilla Firefox on all platforms.
