The user interface in all HubSpot hubs and views include an extreme excess of extra padding and margins around every element.
An option to select a ‘compact’ mode would allow those who work throughout all the hubs, every day, to be more incredibly more efficient.
There are many ideas submitted that are specific to Contacts or Deals hubs, but it is an issue throughout the platform. Personally, my browser zoom is set to at most 80% in order to be somewhat more effective.
This is an essential feature that should be implemented.
