Something that was annoying me on one of my sites was that custom links I’d set up in my main navigation menu would open in the same tab, replacing my site in the tab.
I prefer links to external sites to open in a new tab.
I thought that this opening in the same tab thing was a peculiarity of WordPress.
Turns out you can indeed open any menu links in a new tab if you want to.
There’s a hidden setting you need to access to enable this feature.
