More than you wanted to know about Laravel and M2M

One approach is to create a scaffold for the M2M table and enter the mappings there. I did:

php artisan make:scaffold --schema=name:string person
php artisan make:scaffold --schema=todo:string todo
php artisan make:scaffold --schema='todo_id:integer:foreign,person_id:integer:foreign' PeopleTodo

Then, I had to make some changes with the each of the MVC. Maybe I'll get around to post about using Form:: and  an example where the pivot doesn't have a scaffold but where each class has and add/delete drop down. In any care, here are the raw diffs.

Debian 8 and gnome 3 notes

https://extensions.gnome.org/extension/120/system-monitor/

gsettings set org.gnome.desktop.wm.preferences button-layout ":minimize,maximize,close"
Tweaktool can at least turn them on.
