PRO: Changing the User login (lab menu) page

[rubenig80]

Hi all,
Is there a way to change the look and feel of the initial page a PRO version user finds when login in.
This is the lab list page - aka Lab Manager page.
We would like to
1. block the "edit" button when the lab is locked
2. add a welcome message or a text object to this page

Thank you.
Ruben.-
