Hello,

In the social share there is no option for Instagram.

Is there a workaround?

The print button will be part of the styled buttons collection, similar to the MailTo and SendEmail buttons. 

There are a number of useful parameters to Twitter's Tweet button that it'd be great to set using the RadSocialShare interface, notably the "via" parameter, which tacks on a related Twitter account to the end of a tweet, as in: "Check out this great site! http://www.url.com/ via @GreatSites", and the "hashtags" parameter, which tacks on hashtags. Available properties are listed here: https://dev.twitter.com/docs/tweet-button#properties.
