When looking at the 'watched tags' sidebar-widget accross the SE-network
it catches the eye that (even without those two beautiful free-hand circles ;) )
The widget-header-text is aligned with the SVG image, but in the button below the text is vertically set off by around 0.15em compared to the SVG image (eye).
I fiddled around a bit and got an appealing result:
by changing the line-height of the class
which now gives a more consistent look and feel to the layout of this widget.
But since the class
s-btn is used on various other places in the markup I suggest to add alterations either to the class
js-show-add-watched or to add a new and unique identifier.
I am using Google Chrome version 70.0.3538.110
You may now crucify me as a pedant ;)
