Logitech MX Master & Linux

[orinoco]

Hello,

it's time for a new mouse and I'm thinking about buying the Logitech MX Master. Is here anybody using this device? Is the side-scroll-wheel working with eg. Libroffice Calc? How can I use the extra thumbutton. Maybe for the window flip view in KDE (Control+Tab)? Any tipp or hint is welcome.
