Login & Color Customization
When you login to Hubspot, the top right corner shows the account name, not the username. There is nothing identifying to indicate who is logged in - and this can create an issue when people from the same company are accessing Hubspot from the same computer.
The easiest way to fix this would be to show the name and email of the person logged in somewhere at the top of the screen. What would be even better, would be to allow users to customize skins for their own viewing experience. Aside from personalization, this would allow people to easily identify their set-up when logging into the app on a shared computer.
