A new Windows 10 utility called TaskbarGroups lets you group shortcuts on the taskbar so they can easily be launched without taking up a lot of space.
Once you pin a group to the taskbar, you can click on the pinned group to open a small overlay containing all of the grouped programs. You can then click on the desired program to launch it.
TaskbarGroups was developed by Jack Schierbeck, who released the source code on Github
just a heads up and another tip
If you are concerned that malicious code is hidden inside the precompiled versions, you can always compile it yourself using Microsoft's free Visual Studio Community compiler.
and an executable version that you can download if you do not wish to compile the program yourself.
