Investigate potentially interesting addons

[ineagu]

We can look at our themes/templates needs and try to 👍

1. Add 3-4 free widgets ( would get automatically in OBFX as well )
2. Add 3-4 pro widgets

Ideally, we would also add extra settings/features/layouts for the free widgets in the pro version, so users can purchase not only for NEW addons/templates but also for ENHANCEMENTS of the existing add-ons/templates.

The primary goal of the Elementor add-ons & templates efforts is to enhance our themes offering, the PRO plugin itself is not a MAJOR focus on his own regard, however, if we can signifiantly improve the current state with the not huge amount of work would help.

cc @selul (not sure who's in charge of this one, is pretty closely tied with templates directory for now and themes efforts )
