Hello dear Odooers,

I'm working working on my first project, so please forgive me if this question is basic :)

I've added tabs to my contact form layout, but I haven't found how to place it immediately after "contact addresses". The drag and drop does not seem to do anything. 

I've tried the view editor in debug mode, but my custom tab does not appear there, only the stock ones. 

Where should I look? 

Thanks!

Damien
