I believe there are plugins that can do linked widget titles, so you will need to look for that one.
As for the other part…you can add a link to text or images and wherever you have access to the code view of your content such as a text widget, post, or page.
This is what my home page looks like under text editor – there is no text or code for me to edit or add links because nothing shows up on the home page or blog page, all other pages show text and code as they should. HomePage.jpg
Sorry I think you’re missing the point – if you go to my website – http://www.alexandriaevents.co.uk you will see that there is content on the page, but when I open it in editor there is no content showing.
Ignore the question of adding links, as I know how to do that – my problem is now that there is no text in the editor for me to edit? I’m assuming that this theme works on wordpress 3.9.1 and that it was tested following the update. As there is no explanation for why my home and blog page show no content in text editor, while on the page themselves there is clearly content.
