I've created a simple, yet easy to use GUI for the realm and mangos databases. Currently it's in it's infancy, but I will be working on it more and more over the next few days. This is a beta build, so it's not quite complete and may have some bugs.
To use it you must goto the Settings menu under file, and input your database information. In the tools menu, you can lookup items, it will give you their .additem code as well, for easy reference. It will also show you the thottbot page for the item.
Any and all input is greatly desired! Let me know what you think, and if you have any feature requests!
I know that there is already a mangos DB manager (Mangos Database Handler) but I've come across SOO many errors, and issues dealing with that version, that I figured making my own would be good.
