If you have a frequently accessed tab that is open for a long time, you may want to position it at the beginning of the list for easier access and better tabs organization. The new PriorityGroup add-in lets you add such tab to the priority group and will keep it at the beginning when this tab is open:
Adding a tab to the priority group
Priority tabs are identified by tab name and work globally across all solutions. To remove a tab from the priority group, right click on the tab and select Remove from priority group.
You can color priority tabs using the new TabsStudioPriorityGroup:Properties.Top property. For example, in the standard Tab Coloring Rule dialog, add the following custom condition:
<Condition Binding="{Binding Path=(TabsStudioPriorityGroup:Properties.Top),
RelativeSource={RelativeSource Self}}" Value="True"/>

The Sorter add-in now recognizes if PriorityGroup is running and sorts priority tabs first:
Sorter and PriorityGroup sort and prioritize tabs
PriorityGroup will be included in the next Tabs Studio release.
