I wanted to see how Krita and Photoshop handled their strength/depth sliders differently. I did this with the multipy texture mode and all pen pressure settings disabled. In Krita, as the strength goes down while a texture is applied, the brush starts to disappear. In photoshop, when the texture goes down while a texture is applied, the brush gets darker and darker. Even with the depth is at 0%, the brush can still be seen.
This matches the explanation @C2CL wrote about how Krita and PS applies texture density/depth differently compared to krita.
I think this would be a useful feature to be able to optionally use Krita’s strength/texture density setting in “PS Mode”. I would also really like a lot to be able to apply textures in “stroke per tip” mode. If it’s possible. I’m extremely grateful and feel lucky that more texturing modes were even added in the first place! 
These new texturing modes just add so many more possibilities for making brushes.
But if there was a “stroke per tip” mode added. I think it would be easier for me to create marker/copic brushes that look like
A lot of these marker brushes have a texture that looks that realistic because the texture is applied to the whole stroke.
I agree that if the rest of these proposed features were added, that would achieve pretty much all the functionality that could be possible with the textures.
