Where are the images located for the drag and drop buttons on the toolbar? Can tooltips be added to the buttons so that new users will know what they do?
I misunderstood I think. The file where you can edit the toolbar is located under the /sitecake folder and is called editor.cnf

hitcom, thank you for your reply. I am trying to figure out how to make a tooltip appear when the user hovers their cursor over each toolbar button, similar to what is show here:

I understand. I’ll have to leave that question open for Nik or Predrag, since it involves going into the code a lot deeper. I believe it is hardcoded somewhere in the many files and folders. 
Hi, unfortunately there is no possibility to add tooltip (title tag) for toolbar items, but it’s something we’ll probably add in one of future releases because it would certainly be nice to have those.
I’m not very familiar with coding javascript, but would it be simpler to just have alt tags for the images associated with each menu option until you have a chance to get the tooltips implemented?
