  1. How to make that every stroke of a brush I make is tapered ?
  2. Is it possible to change the thickness of the taper effect ?

Not possible currently. Krita's raster brush engine cannot do post-processing which is necessary if you want to taper the end of the stroke, and the vectorbased calligraphic tool needs an overhaul that was up for a stretchgoal last kickstarter, but people chose for python support and svg import/export.

It it possible to do it with normal brushes ( not vector ones ) ?

No, Krita's raster brush engine is not capable of post-processing which is necessary for this.

When will Krita have this feature ?

Features happen when someone codes it. Nobody I know is planning to work on this at the moment. You might have to do it yourself, or get someone to do it for you.

Would it be possible to add this dynamic tapered stroke to Krita's vector graphics toolset ?

Technically, yes, practically you need to find someone to code it.

I will going to think your questions in a totally different way (which may be wrong, and not what you asked) and understand it as if you want tapered strokes that are pre-set on the brush, as Wolthera and Boud explained, no post-procession can be done to any stroke, but you can have "tapered" shaped strokes in the "normal" brushes using the sensors of the presets (manipulated with the pen pressure or with time, speed, etc.).

This is just a note not only for the OP, but also for any one else new to Krita who reads this and may think you can't stroke with "pointy" edges at all in Krita's raster painting. :)

I was thinking if one would add bezier path, one could adjust end vertices to be tapered in side bar toolset.

Do you still talking about vectors? I think your best bet is to keep using Inkscape for it then just copy/paste them in Krita for raster editing. Krita's vector is still very basic.

If by bezier you mean the assistant tool, you can control the raster stroke from the preset sensors (in the preset editor, even shows you at the top how the stroke would look like), here is a stroke of mine using the assistant tool and applying different pressure on my pen.

I also would suggest to let us know what kind of artwork you want to accomplish, thus would be easy to suggest workarounds to the issue. :)

I've tried working on this for a few months, and then had to throw away all my code because I couldn't figure it out and the branch became too hard to update. This will probably need someone who has more experience than I do. The last time we put this up for a kickstarter stretchgoal, the goal was set at 4500 euro for a reason: it really isn't that easy to do.
