Hi,
I want to add extra functionality to the standard editpage, namely a popup Google search function for lyrics. In 1.3.10 I did this by adding extra <input> tags and javascript to one of the system messages, but this doesn't work in the new 1.4.0 (and rightfully so!).
How do I go about adding a textbox, a button and some popup javascript to every editpage?
Thanks!
Greetings,
Patrick
