By default, in a Contact, the Details section takes up 2/3 of the screen and Activities are confined to 1/3 of the screen. This week they wanted me to resize the Details and Activity sections. Last week, they asked me to figure out how to bring the Details tab to the foreground when a Contact record is opened. In an effort to increase Lightning adoption, I am meeting regularly with the sales reps to get their feedback on Lightning.
