please show FX-ON/OFF in audio track mixer

Hi!
Sorry if I missed something, but as far as I can see for now, there is now way to distinguish if an audio-plug-in is switched on or off in Audio/FX-Mixer. I need to switch through every single plug in to check if its switched on or off (and to check this little round always grey FX-symbol). 
Especially if you have a weaker PC, working with 4K  footage and modern AI-Tools its essential to temporarily switch off FXs. And it's nice to have a global switch-off-button for Video material, but there no such a button for audio. So its a pain to check all plug ins for on or off state and to remember them (which was on which was off, when you want to render)

1) Please change color or whatever to be able to distiguing immediately if an audio-Plugin is switched on or off #essentialwish!!!

2) Please give us a glocal FX-off/on-Button for audio.

3) It would be a dream if you introduce a preset-manager for audio plug-ins (incl. VST). To save at least a 5-Channel-package would be a start for that.

4) an Audio-track- color or any other way to distiguish channels. or at least normal channels from submix-channels. 

If there are solutions for those 3 situations I would be glad about any help. 

I don't need a full audio channel matrix in all directions. But seeing On/Off must be possible to see. And the global audio-fx-off-button would be a huge relief.

Thank you! And looking forward if you can make that possible.
