Expected Behavior

Heading should be able to fill the container space as an alternative to being a constraint to max-width, using a fill prop. Similarly to how Paragraph works with fill.

Actual Behavior

No fill option.

Thread from

The DatePicker component is already created and it's functional, but it was written some time ago and it can be refactored (migrating from class-based to hooks). In order to achieve a good result, we also need a good test coverage.

Feature request summary

Make the clear button on a filter disappear if I need it to!

Rationale

On a filter where one option must always be selected, I don't want to have the 'Clear' button there especially when it is never clickable.

Is your feature request related to a problem? Please describe.
I use theme-ui on daily basis on personal and work projects. The documentation is quite large and I just want to remember something that I used before so I navigate the whole docs to get it.

Adding search in docs page will make it easy to remember things fast instead of navigating the documentation.

**Describe the solution

The background-color for .euiButtonGroup--compressed .euiButtonGroup__button--selected is set to a very light grey #e9edf3, while the equivalent non-compressed, eg. buttonSize="s" equivalent has a way more contrasty anthracite color #69707d. Is it possible to make the compressed version darker? It'd also need the color to be flipped to white.

Hi, I am using atomize for a toy project. I noticed that the collapse atom is not very snappy in it's animation, I'd like to speed up the animation. How to do this? Thank you!
