An implementation about (re)posting timeline items to groups

Hello everybody;

Due to my users continuous feedbacks, I wrote a custom module (which is not an una module) for sharing timeline contents to multiple groups at once.
We can add our own comments etc while sharing.
Posting here pictures to have ideas for professional module developers. Module core is written from ground without using UNA functions, but database structure. As everything is very consistent in UNA database it was not difficult to understand the functional structure.

We share the timeline item through social share menu:

İt takes us to a page where it's possible to add own comments before sharing. In this page also there is a preview of the post. And we can select the groups those we want to share the post.
Groups are orginized as Groups that the user is admin and groups that the user is member.

After sharing a report page with the groups shared

And this is how it is seen in group page.
