Thought I would share what I'm working on for the marketplace. These are the upcoming addons that I'm working on and will soon be available for 5.7.

CameraCRETE - Responsive image slider with lots of options. See the legacy version here:http://www.concrete5.org/marketplace/addons/cameracrete-slider/...

Daily Message - Display a custom message for every day of the week.

Legacy Pack - Several of my most popular legacy addons in one package!

EZ Event - Front-end block to display event info in a nice format.

EZ Modal - Front-end block to display various types of content in a responsive modal.

EZ Print - Make any area on a page printable. Will include image gallery with print option.

EZ Product - Front-end block to display simple product info. Paypal, Stripe, Ebay, Shopify, and others.

EZ Text FX - Display a text header with various text effects.

I'm also working on a bunch of industry-specific themes, such as:

If you have questions or ideas, please feel free to share.
