Microsoft's Latest Windows 10 Preview Brings Improvements To Sets And Tabs
Microsoft does note that drag and drop for Microsoft Edge web tabs within Sets isn’t supported yet and that users might experience a crash if this is attempted. The update also supports moving between programs tabbed together with Alt + Tab. One caveat is that if users have multiple Edge windows in a set, only the most recently accessed is available via Alt + Tab cycling.
Microsoft has also updated the Settings for Sets via Settings --> System --> Multitasking. Sets has its own section on that page and it is searchable by typing Sets or tabs. A setting to control the Alt + Tab behavior is also located in this section. Other improvements include updates based on feedback for File Explorer and Sets.
Microsoft also added a new UI for easier opening of new tabs and windows in the file menu and in the context menu when right-clicking on a folder. An option to open those folders in a new tab is now included in that context menu. New context menu options for tags and sets are available on right-click as well. A bunch of other changes are also in this build with Bluetooth battery percentage in settings for devices and Windows Calculator is improved. The calculator can now calculate square roots for perfect squares. All the fixes and updates in this build can be seen here. The last update introduced "Cortana Show Me" to Windows users.
