Good day! I am posting the “wish” here as it is the app that brought me to the need, but I feel it applies to all apps.
The ability to customize the css is fantastic, but as users we lack of the proper information to do so on most apps.
It would be helpful that within the same screen some useful paramters to customize each particular app are shown, even with examples that one can “teak” for its own needs in order to match our websites.

Hello Agustin,
Thanks a lot for adding this idea here, it sounds reasonable and really nice!
I agree that it would be great to provide some help regarding the CSS, and we’ll try to think about it.
Thank you for helping us!
Hi folks, just in case I’d want to share that we’ve released an MVP version of public CSS codes!
