I can not thank you enough for adding the button templates!
On my first run playing with this I did find a small issue. When adding a park button it is requiring the same number of digits as the extension.
It would be nice to allow single digit park. I have a number of sites with 2-3 park buttons. I set them to 1,2,3 to make it easy for everyone.
I tried using 0001 and the template excepted it but the devices error for numbers starting with a zero
If I am forced to using 1000 and not 1 I will live with it just to have the templates.
