Documentation in theming.md seems outdated

[djschilling]

Steps to reproduce

I wrote a custom config for element web. Changing some colors worked fine. But some of the variables seem to not work anymore as described here.

• Setting avatar-background-colors does not work
• accent-color does not work and seems to be replaced by just accent
• warning-color does not work and i could not find a replacement for it.
• other variables like quinary-content are working but are not documented

Is there somewhere a complete list of variables that can be used here?
Is it possible to override the letter spacing for the font?

Here is the current state of my theme:

The whole approach to theming will change with Compound but the concrete details of that still need to be worked out. In the meantime, we should at the minimum add a disclaimer about this known to be broken in the docs.

Is there a status on when the new 'Theming' and its documentation will be in place?

I'm not able to answer this anymore, sadly, but @langleyd might be.

The docs got fixed at some point
