With this plugin you can create multiple galleries, all filed under “Gallery” page. 
Very easy to use, just install, and start adding galleries in your Gallery section in admin. 
Pictures are added in each gallery with the help of WordPress’s Media Uploader. If you want a certain image to show up as the gallery cover instead a random one, set it as featured image. You can select two sizes of the images: one size for gallery cover images, another for thumbnails shown in each gallery page.

Multiple Form Instances Add-on for Gravity Forms is used in conjunction with the awesome Gravity Forms plugin.
Usually, when you use multiple Gravity Forms with AJAX enabled on the same page, this causes issues with multiple form submission & error display, infinite loading and other issues.
This plugin addresses this issue, allowing multiple forms to be displayed on the same page without any issues.

I have the same subscribe form in a modal and in the footer. This would not have been possible without this plugin!
