Question about visual composer

Hi support

Please I have 3 questions to clarify

1. visual composer is not “behaving” properly on the site, when a text box or any other graphic element is being edited, clicking on ‘save changes’ doesn’t close the window. It might save, but then have to click on ‘close window’ to close the window. In the past, clicking on ‘save window’ will close the pop up window

2. we ave built the site using the elements in visual composer, but if I want to remove visual composer plugin, is there a way to keep the site as it is with editing using classic or fronted mode?

3. what plugin can I use if we want to add social media icons on the top menu but not as a slide out menu?
