Hubspot can be more flexible in term of segmentation of the audience. It took a lot of time to change the filter when there is a lot of layers. Suggest to add a button, so that filter can apply to all. For instance, whenever I created a list, it would be good if the hubspot can have one button 'apply all' such as 'opened email' for different audience. So that we do not need to click and choose one by one.Also, hope that hubspot can speed up the loading time of the created list as it usually took 20 to sometimes 30 minutes to create a list.
