Does the job, but needs improvements

Some possible improvements:

• include_front() should only run where needed (product lists)
• The plugin tries to load the jquery.lazyloadxt.min.js script that doesn’t exist (at least in the free version). This is a page-loading performance killer.
• Configuration is tedious, you have to save each tab’s settings individually. Would be solved by loading all the tab contents in the same page and use javascript for tab-switching. I understand you use the settings API, but it’s easily doable. Also, at least in my case, options get only saved the second time you try, not the first one.
• load_plugin_textdomain() should be called in the ‘init’ action, not directly at the root of the plugin’s code.
• The load more button href should be the wordpress url to the next page.
• Would be awesome if it used the history js api to change the URL everytime you clicked the button. And the nail in the coffin would be that the URL changed according to where you are scrolling in the page.
