I am such a complete technophobe, and so when I realised that to get a sidebar, I'd need to add some code into my site, I wasn't sure if I could do it at all, let alone have it looking good. However the code works really well, the instructions are clear, and I was even able to add in a divider in my brand colours! See it in action here www.leahleaves.com/leahs-blog
My theme actually has a sidebar, but I have a blog in two different languages and I wanted to have separate sidebars for both blogs, which by default isn't possible. Thanks to this plugin, I can now tailor my sidebar content to the language of the person who visits the blog.
