Use Case Question

Hi All: I am interested in the Pro version of Draw Attention as it seems like it will support my use case, but I am having trouble telling (I can purchase it and utilize the refund policy but am trying this first) if the pro version will do all I want, much of which I’m hoping can be done with custom code. So I am hoping to validate whether my use case can be done. I think in some respects I have “Pinterest” functionality in mind…Using Divi builder and tables, I would paste the Draw Attention short codes into each cell (probably in something like a 4×8 matrix). If possible, am hoping someone can flag any functionality below that can’t be done even with custom code.

1) Users go to a page, see a grid of images
2) Each image corresponds to a topic/subject that we define
3) Users can hover over an image, see a description (descriptions only show during hover)
4) Users can click on an image, and it highlights; they can also click again and de-select (custom code?)
5) Users can highlight and de-select multiple images on the page (custom code?)
6) Modal/popups show data on sub topics, and users again can select/de-select sub topic (custom code….would prefer not to do this on a separate page though that may be necessary)
7) A save button allows users to save selections to a database (custom code)
8) When users re-visit the page, their prior selections are shown, and they can change their prior selections to new ones

Thank you
