I’ve added several Visual Studio commands to access Tabs Studio functions using customizable keyboard shortcuts, toolbar buttons and menu items:

VS keyboard shortcuts options for Tabs Studio's commands

VS customization for Tabs Studio's commands in toolbar and menu
Full command name | Toolbar button text | Command |
---|---|---|
TabsStudio.Connect.About | About Tabs Studio | Open the Tabs Studio About dialog |
TabsStudio.Connect.Settings | Tabs Studio Settings | Open the Tabs Studio Settings dialog |
TabsStudio.Connect.CloseTab | Close Tab | Close Selected Tab |
TabsStudio.Connect.NextTabExtension | Next Tab Extension | Activate Next Extension in Selected Tab |
TabsStudio.Connect.PreviousTabExtension | Previous Tab Extension | Activate Previous Extension in Selected Tab |
Usually, tabs do not group more than two extensions and single Toggle Tab Extension command would suffice instead of two Next and Previous commands. But, for example in C++ projects we can have three .cpp .h .h [Design] extensions in a tab. Theoretically, the number of extensions in a tab can be even more. Next Tab Extension command activates the first extension when the last extension is currently active, so for two extensions it behaves exactly as hypothetical Toggle Tab Extension.
Next Tab Extension works only when, for example, both example.h and example.cpp files are already opened. Some add-ins for VS allow switching to example.h even when only example.cpp is currently opened. With multitude of extensions for grouping that Tabs Studio supports, I’m leaving this more advanced functionality for future versions.
