The Component Development Kit as of now supports only Non UI components and lacks multiple language support. This proposal aims at upgrading the Component Development Kit to the next level. Enabling multiple language support as well as visible UI external components. Another ambitious feature this proposal offers to implement is support Background processes. Enabling more flexibility and widening the range of Apps made with App Inventor. Some minor tweaks largely requested by the user community has also been planned to be implemented during this summer. The Projects will be selected or done as per the priority of community.
