Q: A link can be specified with spaces {{{[Can We Display]}}}
Is there a way in ~ViewTemplate to have page names split
so they are displayed with spaces? That would be more
readable.

A: Yes.  Put the following in your jspwiki.properties:
{{{
jspwiki.breakTitleWithSpaces = true
}}}

This will only affect the rendering of the page heading, not any functionality.

Excerpt from the configuration:

#  Usability niceties.

#
#  If this property is set to "true", then page titles are rendered
#  using an extra space between every capital letter.  It may make
#  page titles readable on some occasions, but it does have the
#  drawback of making the titles look a bit funny at times.

jspwiki.breakTitleWithSpaces = false
