System Tray Icons (Kde/GNOME)

[RiemaruKarurosu]

It's weird when I close NoiseTorch and you're not sure if it's running on background, this could be weird for new users.

Describe the solution you'd like
Add a Systray icon to access noisetorch, like skype or steam one.

KDE

Gnome SysTray Extension

Alternative
For gnome there is the new quick settings menu where you could add something like caffeine or GS extension but this solution could be complicated and even GNOME exclusive or not possible with GO

I think part of this ends up being that when NT is closed it really isn't running in the background anymore, it's just that the ladspa plugin is still up and running. This would probably require some degree of fundamental design changes but I still think that it would be an overall useful thing to have.

In regards to dealing with GNOME, I'd personally rather keep things as cross-platform as possible. I don't know if the GNOME devs have decided that things in the quick settings menu can pull from the normal systray or anything like that, as I haven't used the DE in a long time. That said, like you mentioned, the systray extension works and is included by some distros by default (Ubuntu, Pop, etc). With that in mind, if this is implemented I'd definitely opt towards that solution.
