New Windows 10 Insider Preview Fast and Skip Ahead Build 17666 - May 9 Insider

I have sets, but basically can't test anything, besides that apps have multiple tabs, which can be PITA, since you never know, how the next app will launch...in new tab or in new window

Can't save them or anything... I'm blaming this:

You can change in settings to have new items open up in a window or tab. It's in the multitasking.

Also, It's amazing how excellent some teenagers can build themes for Win10, and yet M$ can't seem to put together a decent dark theme!!!!! Last point on customization, we are in the 21st Century, and they are still using manilla envelopes for folders, and ridiculously simplistic icons for computers and drives. Do these guys have any imagination, or style??? Off my customization soapbox, and getting on my functionality soapbox. BLUETOOTH is screwed up again. The last few builds it was rock solid. I didn't have a single problem out of BT over the last three builds. But now...

Sets still working with Mach2

Can you save groups of Tabs???

Win+ V interesting, looks like a great idea, but I'd like to be able to move the box around. (Noticed you can scroll through all the saved items with your mouse wheel)

I think my 17666 is preparing to prepare me for the preparation of the 100% Preparing to install preparation stage!!!
