If you scroll down to the roadmap, you can see that system trays are supported. We don't yet support native context menus, but that would be a relatively simple addition. Our GitHub readme has a table comparing Electron's and Tauri's features, do you think it would be useful to include that on the website landing page?

So it would make sense to split the roadmap into what already exists, and call that the feature list, and the rest can remain as the roadmap.

Then provide screenshots/code samples for each item in the feature list.

That sounds like a solution. Or just add some screenshots/code samples to what is already implemented in the roadmap.
