Hi there,
is there any way to control the system options from the panel? For example, I wish to have a toggle in the site blueprint to enable/disable the whoops option. It’s much easier to jump into the config and switch manually.
No, this is not possible, because you cannot call the $site object in the config. There’s a feature request somewhere… But this is usually not something a user should control, as they only edit content anyway and you don’t want to accidentally expose error messages.
Of course, I understand! But for global E-Mail settings and the whoops it would definitly make sense!
I think you could work around this by storing the information in some file and then read from that file in your config. A bit of a deviation, but possible.
Yes, really a bit strange 
I will change it manually or wait until $site is available in Config
