To Save the site as a template you can follow this steps.
Open your the site with SharePoint Designer
In the ribbon go to Site Options
Locate the option SaveSiteAsTemplateEnabled and modify the value to true
Since the site template is disabled in the Publishing sites the option Save Site as Template is not available in the Site Settings you will need to navigate to the page directly: http://yourdomain.sharepoint.com/_layouts/savetmpl.aspx Provide all the details and click OK after a couple of minutes you will have the WSP site template generated
Note: If you have apps downloaded from the store they could prevent you to save the site as a template if you are facing this scenario you will need to uninstall the apps first.
Create a site based on the template will require a similar environment this means that you will need to have the same features installed and activated in the site collection where you want to install the template.
The "Recent" section in the left navigation of SharePoint 2013 Foundation is incredibly annoying.In my opinion, it’s something that should be off by default, but we should have a way to enable it as desired through the user interface.Unfortunately, it’s on by default and if we want to turn it off, we can’t.It’s not possible.
Hide “Recent” section on one page
1.Edit the page
2.Add a Content Editor Web Part to the page
3.Paste this code into the Content Editor Web Part, making any changes you need to.
This assumes that all pages in your site collection are referencing the same master page.Of course if you have multiple master pages and site collections, you’ll need to do this for each master page being used within each site collection.
1.Edit the master page of your site in SharePoint Designer 2013 (other methods work fine as well).
2.Add a reference to jQuery in the HTML section of your master page.
3.Add the jQuery script to hide the “Recent” section within the “PlaceHolderAdditionalPageHead” content placeholder.
