when you get to know them, it's just excellent!
for example, there are 4 upload buttons, but they basically do the same stuff, it doesn't matter what you upload, right?
so, in Write options - post and Write options - page, i wrote this into "Your own options"
- first column (ID or class): your own arbitrary name, in my case Excess Media Buttons
- second column (Option): the div id's you wanna hide, in this case #add_image,#add_video,#add_audio
. then you update,
. and after refresh you're gonna see a brand new option with the name you gave,
. now just tick the users you want to hide the buttons from,
. another update
voilà, no more excessive buttons
ps.: to find elements id's, use Firebug inspect element, or Safari's built-in inspect element
