I don't know how I ever got along without these. If you don't have these, and have pages to build in page builder, you're really missing out!
3. Block Tools
Page Block keys gives you all kinds of options to personalize your custom html plocks for the logged in user.
Per page head injections is really useful if you want to call a javascript file that you want to use on your custom page. One use is to call Jquery accordion or tabbed content functions that are not normally loaded for page builder pages. There's also a ton of other Jquery plugins available that you can use to build some really unique pages. This mod makes it really easy to use those plugins on a per-page basis. Great Stuff!
Block Tools... allows you to easily change the design box for any page block.... great for getting rid of that often useless page block header. Create php and html blocks on any page, copy blocks from one page to another... very cool.
Nice Work Deano!
