Start10 is working well for me but one thing that is driving me crazy is that in Win10 the shrunk the size of the taskbar icons, apparently from the 32x32 size used in Win8.1 to around 22x22.
There is a Win10 taskbar option to set the size to large or small but I'm at the large size and they are much smaller than they were in Win8.1.
Its appears there is still enough vertical space for the larger icons but they shrunk them to leave room for the bars they place under them.
It would be a nice enhancement to Start10 to have an option to use Win8 sized taskbar icons.
