Whenever we want to re-use widgets from the former child SplitterOrView,
we must make sure that this doesn't delete it later on.

Before it would use Courier on all platforms, which didn't always look
nice. Now it uses the configured text editor font.

The file paths are now also normal size, at least personally I don't see
why they should use a larger font.

Removed "void" from functions that take no parameters, removed a few
"get" prefixes, etc.
