Social Links in new 5.7 Version don't open in a new tab / window1 user found helpful
You can change the behavior of the Social Links block using a custom template.
I have attached a custom template to do this.
- unzip the attached file into your application\blocks folder
- in edit mode, click on the Social Links block and select Design & Custom Template from the menu
- in the second menu that pops up, click on the gear icon
- in the Custom Template select dropdown, select Open In New Tab
The Feature block accepts internal and external links, so I think that is more of a candidate for a custom template.
Opening Social Links blocks in a new tab by default sounds reasonable.
