Hi,
I have a suggestion.
I love Start10 but what I dislike about it, is the dated UI in some aspects, mainly the jumplists and the scrollbar. Win10 is very inconsitent as it is, so maybe the devs will consider it.
In the regular Windows 10 Start menu, the scrollbar is very tiny and will only extend when you hover over it, which looks pretty nice, whereas in Start10 it is always visible:

Same for the jumplists, like when you click the shutdown-button:

I know this might not be a priority and maybe users dont even agree with me, but I just wanted to throw the suggestion out there.
