Is there a way to configure the font/font size of the text in sidebar and pane/surface headers

[preetmyob]

I love the idea of the sidebar that notifies you of what's happening across multiple sessions, as I use multiple terminal windows for parallel work.

I can configure the font/font size of the text in the main content area in the settings. However, I can't see a way to configure the sidebar font/font size right now. As someone who is slightly visually impaired, I'd like to be able to make the sidebar a bit bigger.

Can anyone point me to the right direction, please?
