Where space is tight
Where space is tight, such as in your blog's sidebar, you use a small Nifty Slideshow, obviously. This works just fine when the available space isn't too restrictive.However, a 'prettiness' issue arose for very small width slideshows and that was that the navigation buttons, search box and auto-titling could be just too big and impractical for the space available.
New Nifty setup option
To resolve this, I've now added a new option in the Blog/Website slideshow generator only section. It's a checkbox and checking (ticking) it suppresses them as a group. You'll see that reflected in the live preview at the top of the setup page.
To be clear, this won't affect Nifties you're making to share on social media, just the code snippet stuff for page/blog.
