What Plugin do I need for Simplemarket

Here are the instructions:

Activate the FrameMarket or GridMarket theme.

Under Theme Options > Set up your theme find “Type of Header” and choose “Site Title” and then find “Show global or just that main shop products on the front?” and choose “Local.” Press Save Options.

I am using Simplemarket, not Framemarket or Gridmarket, and was told I would need to develop the theme (which I do not have the skill to do) or find a plugin that will do this for me. My last question went unanswered in the thread I started about this problem, so I am starting this as a new topic in hopes of getting some faster support.
