i am using it on a multisite but it is not ideal. problem is it does not define between keymaster and administrator. so if you hide something from an admin you ultimately hide it from yourself. that’s the experience i have had and maybe the author can point out what i am doing wrong.
Would be great if the plugin author could add another column for Network Admin/ “super admin” to keep settings separate from sub-blog admins. I’m sure all network admins will find this plugin very useful then and that will make Adminimize 100x more powerful.
