For the size of predefined brush, it depends of the brush and especially of 
its original size. For the size of "auto brush" very often. It is not a 
setting that depends on your style of painting, but on what you want to draw 

Also while it takes space, it actually increase the precision of the slider. 
And I don't think I would want to go to krita settings to be able to switch 
between the 0->10 range and 0->100 range for brushes.

Same as for size, I remember someone on irc that was confused as to why size 
would go from 0 to 200%. I am not sure why it is so.

ok so "mirrored" "no mirrored" would do... but a bit long, so maybe an icon. 
Or a preview.

Because it is a fade :) Personnaly, I don't care for the name, I just want

yes, value is vertical legend, sensor is horizontal legend.
