We can never have enough widgets, modules, templates in Wordpress! ElementsKit has an impressive arsenal of Add-ons, Ready-made blocks, themes, headers and footers, widgets and, my favorite, Parallax effects.
All of these by their own are amazing tools to have, but what really impressed me about ElementsKits are the following:
1. Multiple headers - have different header menus on different pages - most themes just let you have one global, but with ElementsKit, you can have different ones for different pages. Footers too!
2. Conditional logic - want to display a coupon only on slow days, like Monday, to boost sales? This is for you! Want to only display to certain user groups? You got it!
3. Advanced sticky! I'm a sucker for nice looking animations and clever designs, and seeing the possibilities of this brings me joy.
4. Cross-Domain Copy Paste - if you're doing something on a test site, but don't want to do it again, just copy paste to your real site. Awesome!

And many more! These are just the ones I've been impressed with, but I'm sure you'll discover more. Just check out all the examples!
