TaskbarDock gives you a few options to customize your Windows 10 taskbar.
TaskbarDock is currently in beta and still can use some work. We were initially confused until we discovered the Setting icon.
There we found:
Show Start Button
Show Tray Area
Start with Windows
Taskbar Dock might be in beta, but we found some things to be interesting and unique, like hiding the entire System Tray. While it could use more features, what is here works fine, and we hope to see development progress.
Some settings might require you to unlock the Taskbar. Right-click on the Taskbar and verify that Lock the Taskbar is unchecked.
