Answer 1

making it lowercase makes it easier for Jekyll to parse and handle the project.

I have a couple of questions for you:

1. Is Jekyll's lower-casing of the category names hurting your site performance or causing you any trouble?
2. Or do you want it for the aesthetics only?

If its the latter, the solution is to capitalize it back again.

{% for tag in page.categories %}
{{ tag | capitalize }}
{% unless forloop.last %} • 
{% endunless %}
{% endfor %}
