Thanks Bertrand, this is exactly what I was looking for. I wasn't expecting the login/logout process to be so easy though :) I'll try to come up with a neat UI for this.
BTW what's the recommended way of integrating new features in existing admin templates ? My guess is I'll have to override a few templates but are there guidelines to make it the less obstrusive as possible ?
First, remember that this extension is really old, and parts of the API might have changed in between. But it shouldn't have got much more complex :-)
Then regarding the UI... if you want to integrate your feature in existing templates, it will indeed require overrides. The goal would of course be to override the least specific templates you can find so that it overlaps as little as possible with existing features.
The first ways that come to mind are:
- new right side menu block - new admin tab (through menu.ini)
