Not that I know yet but will look further into it.
Had this on my TodO-List already, wonder why Imissed to do it =)
You donot need to restore the default skin, you only need to delete or rename one directory as it is described in the instruction ... Maybe you deleted the wrong things on the first try?
1) Will be changed to better visibility
2) Cursors will be changeable later. Until then you may restore the old ones with the method described few posts before.
You could use the normal darktech wch has larger HP-bars or patch them into the DarkMini files like it can be done with the mouse cursors.
Will also be changeable in a later version.
