The threads filter is easy to miss

### Your use case

#### What would you like to do?

Threads can be difficult to navigate, and can be overwhelming. I want to be able to filter out threads in the right panel to only display the threads I was involved in.

It turns out Element already has this, but it's really hard to discover.

When clicking on the tiny text, the options are self-explanatory

I had completely missed this filter. I believe it could stand out more.

#### Why would you like to do it?

To declutter my threads panel.

#### How would you like to achieve it?

I'm unfortunately not great at pushing for visual improvements and will leave it up to the design team :)
