For my eyes the size of text in the contents panel is fine.

I purchased license yesterday and look forward to using this promising product.

The solution that Ben provided earlier is going to be your only option.  Increasing the font size within the help file really is not a solution.  We use the same font size that all other major entities (including Microsoft) use for help production and creation.  The Ctrl + scroll is really going to be the only option to manipulate the font size.  Thanks.
