I've created a dashboard containing a map. My client wants little help buttons on each of the panels so if the user has a question about what something my do in each panel, they can click and see an explanation as well as more information about what actions can be performed in each panel.
Currently, I just have the buttons in a non-intrusive area of each panel (see mockup). Should I try to standardize their location (put them all in the same corner of each panel) or is having them in different areas acceptable?
