They should still appear. Affects individual categories (Friendly creatures,...) as well as master volume.

Good call. Maybe it should stay this way and a note about this behavior could be added under the subtitle toggle.

I agree with Kumasasa. Maybe the master volume Off shouldn't exist, just 0-100%, but let the other ones turn themselves off.
Seems odd too me that subtitles should be tied to volume in this way. In other software/games I've played and even my TV, subtitles come on when sound is turned off. This is actually my TV's default behavior and this makes sense to me. IF I can hear, why would I have the sound on? I wouldn't, I'd rely on the subtitles. Likewise, a lot of people use subtitles because they have to / want to turn the volume off (night time playing, company, parents, etc) and yes, I know about headphones. I think the option should exist to auto turn on subtitles when volume is turned off as well as an option to independently turn off the subtitle category.
I was very excited when subtitles were added, it meant I could finally just play with the sound off (which I already normally do) and I'd still be able to know what was going on in the game. This is probably the single most important feature being added to the game.

Just to clarify, you can turn subtitles on with sound off by setting the sound to 0% instead of Off. The reason this occurs is because the sounds don't even play if the sound is set to off, so the subtitles never get triggered.
But if subtitles will be shown even with sound categories off , you cannot switch off the subtitles of that category.
