Groupy allows you to combine several (or one) applications in one window with the ability to switch between them using tabs.
To group programs in Groupy, you just drag one window to another, in addition, you can add the program to the group from the menu in the tab bar, which lists all currently running applications. Optionally Groupy can automatically group windows of the same application or type. For programs that use the standard Windows window titles, the Stardock program can combine them with the tab bar and then the combined windows look quite natively.
To remove a window from a group, just drag its tab outside the general window, as well as in any browser, for example. Switch between tabs using the mouse or the keyboard shortcut Win + ~. Drag-and-drop files are supported between the tabs, which is probably especially useful in Explorer.
In the Groupy settings, you can select the colors for the tabs and their width, customize the buttons for managing them, the icons of programs and text in their headers, getting rid of the extra visual “garbage”. In addition, you can activate the window grouping option in the same place if you hold additional keys (Shift or Ctrl), use the same option when dragging tabs, activate the tab closing function with an average mouse click.
The ability to specify exceptions – specify applications that can not be grouped together, and about the tool for managing automatically grouped applications – you can turn off auto grouping of windows of such programs in the settings panel.
