Additional post options

Thank you for such nice fronted plugin, spent half of evening with it ??
But there is a question:

When I create a post using standard WordPress admin, I have a plenty of additional options (social likes checkbox, livejournal crossposting options, etc). When I create a post using WP User Fronted I cannot choose anything, so some of these options remains with their default values, some doesn’t work at all. So how can I force WPUF to use some of additional options?

Or if I have a possibility to use [plugin_something] shortcodes, where can I put them in WPUF templates to use in new posts?
Or – moreover – when i have a PHP code like insert_plugin_here() where should I add it to have in all WPUF posts?
