I know this is in the category of “John’s being OCD”, but there is appearance issues with using a horizontal vs stacked logo as the project logo. See below images…
As you can see, on some pages a horizontal logo will layout much better, but others then the horizontal logo looks too small and a stacked logo would be preferred ( or in the case of the last image, it’s resized so small it’s hard to recognize. )
One thing that could help is being able to provide both a stacked and horizontal logo if the project has one available.
