If you''re looking for a Windows application... I initially wrote this for (what was then) Chronicles of the Shattered Empires, and is now Legends of Arcanis. It runs in Internet Explorer. There is no installation necessary. Just unzip the file into a folder somewhere and double-click on the .xbap file. (Assumes that IE is your default browser. If not, then open IE and point it to the .xbap file.) Firefox has an add-on that can be used to support .xbap as well.
If you don't like it, just delete it. No uninstall necessary. It's probably a bit more then you "need" but will have all the bells and whistles to get the job done. I intended it for the Chronicler (Editor in Chief) but I know people who use it as players also.
