Bootstrap compatibility If you are using a Bootstrap template, select which version of Bootstrap your template is compatible with. It will ensure the extension outputs the proper classes for the Bootstrap version you are using.

New The Joomla option loads the Bootstrap version packaged with Joomla (which is the default behavior). All other options WILL NOT load Bootstrap
Show errors Show the errors encountered while creating the view (mostly during thumbnail creation), if any
Load icon font In rare cases (when no icons are shown), will prevent the loading of the icon font library, reducing page loading times 
Load IcoMoon font When selecting IcoMoon icons as default icon or as custom field for an article (through the SYW Icon custom field), load the IcoMoon font if missing
Load Chosen script Beautifies the select boxes with this jQuery script packaged with Joomla

Cache

Pictures
Reset pictures Whether to re-create the image thumbnails every time the page is loaded or not.
'No' will improve server performance once the view is properly configured and ready for prime time
Auto Clear Cached ImageInstall and enable the Auto Clear Cached Image system plugin and automatically refresh the image associated with the article or K2 item you just saved. No more manual intervention needed, all extension instances are updated at once!
Thumbnails cache path The path for the thumbnails created (by default, in the media folder under /thumbnails/lnep).
It is possible to save the files to the temporary folder of the Joomla configuration or the /cache folder
Stylesheets and scripts
Inline scripts Include scripts directly into the HTML source code, reducing the amount of HTTP requests. The scripts are small enough so that writing them into the source may have a better performance than calling them through files
Reset headers Re-creates the cached stylesheets and scripts after style modifications have be made to the view.
'No' will improve server performance once the view is properly configured and ready for prime time.
Note Stylesheets and scripts are cached in the /cache folder. Deleting the cached files from the administrator console (System -> Clear Cache) prevents resetting the Reset Headers parameter to 'yes' when changes are made
