Background
These settings – especially template path hints – are unclear in existing documentation.The Magento User Guide makes no mention of either. My guess is that it’s considered beyond the scope of that manual. I’ve not seen any mention in php|Architect’s “Guide to E-commerce Programming with Magento” so far, either.
Magento Inline Translation
This is turned on by visting your System >> Configuration Menu, and opening the Developer tab (way bottom left). From there, open the Translate Inline pane. Notice our Configuration Scope: “Default.” You can also set this at the website and/ or store level. Here’s what you’ll see:

Magento Template Path Hints
This is a little sneaky. Template Path Hints are controlled by a setting under the “Debug” pane. Visit System >> Configuration >> Developer. But wait. What if you don’t see it?
Chances are, your current configuration scope is set to “Default Config.” You cannot setup Magento Template Path Hints globally. You’ll need to set the Configuration Scope to a website or store configuration. When you do, you’ll see a screen like this:

Magento Template Path Hints
Great, but damn it looks ugly. Is there some easy way to style the hints?
The problem is when u switch it on everyone can see it.
Is there an possibility to limit the view for a group with roles?
I’m afraid I don’t know; I don’t think so, not in Community Edition, anyway. Typically we set up several servers, do our work, commit to version control and then distribute. Yes – everyone has their own Magento!
