How do I get the number of nodes using terms from a vocabulary on the same line together the link to the term page?
Yes. By default, a HTML List View displays fields wrapped in a couple of DIVs, a block-level element. Hence, it displays each field on a new line. To disable this, use the Style Settings > Customize field and label wrapper HTML checkbox for each field to use an element that isn't a block-level element (e.g. SPAN).
