Please give us back the CSS formatting option in Confluence Cloud.

Your supplied styles need serious tweaking to be the best for us. 

Creating a theme is beyond most people. And is a huge effort. And should NOT be required.

We need to be able to inject our own CSS as neccessary.

Remember, it is in your hands to HELP the customer with THEIR needs.

Thank you. I've upvoted that now.

But give that this has been complained about for a number of years now, I'm not holding my breath. 

Atlassian have gone the way of any larger company, making incomprehensible decisions. Quite likely for what they think is the largest common denominator.

Ignoring the people like admins who need these tools to best serve THEIR users.
