Speaking from the viewpoint of design, I'm also not sure that after indentation removal, the direction of gradient in the divider line from the center to the edges is well-grounded. For my design taste, as now everything in the sidebar is aligned along one line in the left (after pixel differences get removed), the direction from the left to the right is more consistent.

Would be interesting to hear from somebody who designed Vector or the sidebar particularly (please add them if you know who they are).

All perfectionists in the world cry tears of blood. WMF Design team should probably too, given their section on alignment :-)

@Volker_E has been annoying me with a lot of off-by-one-pixel fixes lately, let's see if we can get him to look into this one ;)

I think that would be @TrevorParscal. I'm not sure what you mean in your last comment though? What gradient?

Thanks for invitations.

Oh sorry, I'm talking about the divider lines under the headings (edited).

I'd be in favour of dropping the gradient altogether, as we are moving towards more flat design.

Thanks @Esanders, your newly calculated values look great for me.
