Customizable User Interface
I should be able to change the icons that show up in the left navigation bar and the order in which they appear. For example, I do not have email connected to Pipedrive, nor will I ever due to security within my firm. Having that icon show up in the nvaigation bar is useless and wastes space.
Additionally, the main background of every window is a light gray. It blends in too easily with the white content/text boxes. The main background of every window should be a slightly darker gray so they white content boxes "pop" off the screen. If you use more contrasting colors it's easier for your eye to jump to different sections because you can actually tell where the sections begin and end.
