What is the proposed idea/solution?
In any view, you can show or hide fields. As that list grows and more are added, the list gets longer and sometimes out of order based on when things get added. The proposed idea is to create custom sections inside your hide field or x hidden fields menu at the top so you can easily keep track of your fields. When you click on the fields menu at the top, the idea is to have a "create section" button and drag and drop all your fields into whatever sections you want to create.
How does this solve the user problems?
It helps users stay more organized when dealing with a lot of field types inside of one tab for more robust situations.
How was this validated?
Airtable has sections built in already, where you can create sections inside of the views and automations sections. The same ideology should apply to the fields.
Who is the target audience?
Users who are doing more robust and complicated views that have many field types.
