Please help explain settings available for each extension

Your plugin seems great and the free version installed well. Linked to two social accounts well. However now the problem is which pro or extension version do I really need to get the outcome we want on our pages. At least to me, answers to this are not clear by looking at your different extension pages, especially when we find out some singular accounts settings such as instagram allow settings for a max height and thus scroll force, while a single facebook setup does not and may require custom css setup.

So, would this change if we purchased the Combined Streams ext and chose to show them both in a grid together?
And can we show grid in combined stream?
Also, what does FTS Premium include? Does it have all the extensions or instead options/settings the extensions don’t have?

Do you see the type of questions we are trying to answer before choosing?
I see a couple different feature type lists but it’s unclear. Please help me understand which does what, and what each individual extension won’t do.

Thank you for your great plugins!
