Ok, a bit late here is the explanation of the reason why I've modified 2 color codes of subTrail
subTrail is a clone of subSilver with only different colors.
No code line has been modified, even in style definitions!
So as a result, we must respect the color logic of subSilver.
The pb was located here...
The colors of these 4 lines go from the lightest to the darkest.
But in the old releases of subTrail, it was light/dark/light (same color as the 1st one)/dark (same color as the 2nd one).
That's why I changed these 2 colors and here is the result with screen copies...
The translators had no relief. Now they have.
The line was not displayed. Now it is.
And the only change which is a consequence of these modifications and do not fix anything is...
But that's not a problem. It's more like subSilver and the most important is to have different colors to identify each column.
P.S.: the Spanish translation has been add to each archive
