We have a major update scheduled to be released very soon. In this update, you'll see a whole new Shareaholic. We've put a lot of love into a complete redesign with more options, greater control, improved compatibility, and several other enhancements.
Throughout the year and into the future, we will be continuing to upgrade features and options. We take pride in offering amazing products and services to the community and appreciate your feedback. I've relayed your request to the team, and good news! We're adding this feature to our list of product enhancements to be implemented in a future update.
Right now, we do support automagic translation for tooltips and headline text for the Related Content (Recommendations) feature if a translation is on file. Automagic translation is determined by the viewer's browser language setting; you can read more about it here and submit a translation here.
