I want to add some functionality into laravel-debugbar extention

[mstdmstdd]

  Hello,

In laravel 5.4 using laravel-debugbar extention https://github.com/barryvdh/laravel-debugbar
I would like to add some more features to it :
In “Queries” tab near with sql statement to add 2 buttons:
1) Copy sql-statement to the clipboard.
2) Copy sql-statement to the clipboard nicely formatted.

As I see docs it has no such functionality.

I suppose I need to edit it mannually, but I would like to know:
a)If this extension has some events, which could be usefull for me?
b) If I edit this extention, which could be good way not to lose my modifications in next system update?

Thanks!
