Roadmap lacks in-progress details on touchscreen

[jackie-scholl]

The roadmap section of the website contains a chart showing which browsers have support for which features. Implementations in progress are shown with a ⏳, but it's not immediately obvious what stage of implementation they're at. Apparently with a mouse additional info is available on hover, but many users, particularly mobile users, are using a touchscreen more than or instead of a mouse, so they cannot hover over the element. The additional information could be made available on focus, click, and tap.
