Mixer delete track and routing visibility

I saw a post from 2021 but it is still not possible to delete a track, Group, FX channel from the mixer, and that is very regrettable.
I personally usually hide my groups and FX channels from the project window as I mostly want my midi and audio there, so to delete them I have to unhide and delete. PLEASE Steinberg just allow us to manage our track deleting from the mixer.

As for Routing, it would be nice to visually see which channels are routed to a group, does that exist? Several ways, eg when routing is visible, hovering over a group routing area would highlight which channels are sent to it. Or a menu: highlight channels, or show only channels, or color coding to the routing menu, something to see quickly and easily.
Thanks !
