First off, what a plugin! Brilliant idea and design, I particularly liked the tutorial...if only all plugins took you step by step. I would like a lesson from the creator in how to make plugins like this.
I do have some concerns and some suggestions however.
1. I tested it with FB everything worked great except when I checked my FB it had posted an image as the thumbnail I did not want. Is there (can there be) a way to hard code in an image of my choice? I think the Ultimate FB plugin here does that?
2. Some people dont have social media profiles....i know i know but honestly its true. Could there be an option to switch on a small textual button (situated below the social media links) that says "I dont have a social media account can I skip this". Obviously I know this defeats the purpose a bit but it could be very small text and it would be below the social links and the admin could turn it on and off.
3. I would imagine that a lot of peeps using this simply want to share one link (there main domain) or similar links. Could there be a default link loaded into the text field already or perhaps a button which would facilitate that? (I know it remembers the text you put it sometimes but Im just being picky)
4. I notice the "Discussion" and "Comments" nodes are displayed on the add/edit social marketing page at the bottom. Should these be here?
Id really like to see number one above implemented asap, if it is this plugin would be nearing perfection!
