I just finished my first WordPress plugin. It's called Easy Admin Color Schemes. It allows you to manage the color schemes in your WordPress admin area. You can add new ones and edit existing ones. There is also a live preview feature so you can see what the new color scheme is going to look like as you go.
I haven't been able to test it to great lengths yet but I think it should work for most setups. Let me know if you find any problems though.
I have to link you to here for now because I haven't been allowed access to the SVN quite yet.
Again, this is my very first WordPress plugin. So, it may not be as great as some others from people who have made 50 plugins already. :p
Please let me know what you think. Also, please let me know how well it works, if you get any errors, any other features that are a must-have, etc. Thanks! :D
