Hello,
Since that software is e-mail related it would be nice to have "Account" menu with Log in / out options . That way if more than one persons are using the same pc (mouse and keyboard) they could have different settings/preferences applied. Also an "export settings" option is recommended to have so u can use you're mouse/ keyboard the way you like it even if the pc is connected to local network only or no internet connection at all.

At the previous version of the software if you choose settings for Photoshop , Lightroom and etc. there use to be brush size option directly in the menu , don't know why but now they are gone and the only option to have it is if are set as key combination.

It would be really nice if there is an option to leave the mouse led on when mouse is connected and operating. I know it would decrease battery but am sure that many users will appreciate that since the mouse is is looking more "alive" and pleasant with that led on
