The Custom User List macro should have settings to configure the width of different columns. Depending on the field types that are included in the list, some columns end up dominating the horizontal space which crowds out other information.
Example: We have a field for "Personal Intro", which is a Multiline Text field. If this field is included in a Custom User List macro, it takes up roughly 75% of the width of the table/list, which makes the other fields such as User or Location (Text Input fields) become doubled up and crowded.
This could also be solved if the presets for the table were more intelligent, e.g. change the code for the macro so that it doesn't assign such a large percentage of space to Multiline Text fields.
