Newest version is just a change in the readme, no need to redownload it if it is working for you.
Modified Hotbuttons window originally made by Atheena Dawn, modified by Deathfile on 6/14/2003.
The original window contained all 10 hotbuttons and all 8 inventory slots. This one is added to contain 8 equipment slots. Most people do not have every item in their inventory a clicky, so this is meant to be used for those wanting to save hotbuttons without displaying their entire inventory.
It is easily customizable (read the readme if you dont know how to) to change the 8 equipment slots that it has.
