MX Master 3 User here:
I know I can't be the first one to suggest this. But can we please get predefined and customisable options for Adobe Lightroom?

E.g. brush size, adjusting sliders using the side scroll wheel. TBH, believing it would be compatible with Lightroom was one of the main reasons I went with the MX kit.
It's even advertised as 'ADOBE CREATIVE CLOUD AND LOGITECH MIX' - but does it really?

Please, add better functionality to adobe app support.
