Disapointed

I installed this plugin because of the extension that converts the magazine articles to PDF. I’ve been very disappointed. First, the default layout of the posts does not include a post thumbnail. I search high and low to figure out how to add that in. But, every time the plugin is updated it has to be re-added. I purchased the Issue to PDF plugin and found that there are no options in the plugin for customizing, and it didn’t come with any instruction. I was finally given a link to mPDF documentation. But, no instruction on how to apply my PDF template to the plugin. I am not programmer, and this is a bit too advanced for me.
