<pre wrap="">Regarding the logic confusion: the opacity option in the brush editor
controls the mask opacity. That is different opacity then the one in
the tool bar.
The global opacity (in the toolbar) is used to composite the final
dab with canvas.
So there is difference. Now there is slider in the option that
controls both..not sure
if that is good idea.

<pre wrap="">It's of course logical for us, because we know how everything works
internally.
But just try to think like a user who doesn't know what a brush mask is,
doesn't care about
the internal workings of krita and just want to paint.
The user sees an opacity slider int the toolbar and thinks when he will
set it to 30% the brush stroke will
be 30% opaque (ok at least I would expect this :D).
But the previous situation was that this 30% where actually 30% of the
opacity set in the preset editor.
So, when the opacity in the preset editor is set to 70% the overall
opacity would be 30% of 70%.
I don't really see any benefit in this.
I mean I didn't notice this, too (because I know the internals as well).
I just noticed as I read one of Davids mails and it seemed to me that he
was a bit confused
about the two different opacity values.

Yes I was confused by Krita naming and options but reading this
discution, I can understand more where is the problem now (I guess
)<br>
2 big topic are confusing for my user experience with Krita :<br>
<br>
[1] the 2 opacity sliders mess :<br>
- The opacity in the preset editor seams to be in fact a bad named
*flow* parameters ; other software use this label name for 'opacity
per dab' or 'opacity per brushmask' .<br>
- The global opacity slider seams to be a real *opacity* parameters
; used for global compositing of the end result stroke. <br>
ex : ( <a class="moz-txt-link-freetext" href="http://david.revoy.free.fr/forums/krita/opacity-and-flow.jpg">http://david.revoy.free.fr/forums/krita/opacity-and-flow.jpg</a>
, This 2 parameters , (advanced) Artist understand it, and it's
useful. )<br>
<br>
[2] the 2 'painting modes' mess<br>
In Krita actually there is "2 modes" that wan be a bit obscure . <br>
- In 'Build up' , the 2 opacity sliders behave for one as a "flow"
, and other (global one ) as "opacity". Fine.<br>
"Build up" looks like what I know from Gimp and Photoshop. The
behavior is predictable. <br>
- In 'Wash' , the 2 opacity sliders are just an indentation of the
same effect setting ; and there is a weird effect only Krita has ; <br>
a weird alpha self collision with the previous alpha of the previous
dab : ( <a

)<br>
Wash mode was useful for me when I couldn't save the 'global
opacity' slider of a brush preset ; at this time, this 2 painting
modes acted as a switch between 'per dab opacity' and ' global
opacity'. But now I can save the 'global opacity' in build up ; wash
mode became obsolet. <br>
<br>
[X] So, Solution proposed :<br>
1) Name the "opacity in the preset editor" category 'Flow'<br>
2) Include the "global opacity" as a new categorie in the preset
editor, acting as "opacity"<br>
3) This will result of a remove of 'Wash' mode to keep only "Build
up" ; and so removing the choice and option.<br>
4) add 2 sliders on the top toolbar option : "opacity" and "flow"
sync with the preset editor as in Gimp and Photoshop ( <a
