Hide Stacks.... still an issue after 5 years this thread was started. Hope to hear if this is in the product launch plan. Other than that i am finding Airtable pretty amazing. Thanks.

I'd love to be able to hide stacks, more customization in Kanban view please. Wider, wrap text, etc.

Same, please give the ability to hide stacks (empty or not)

I would love to see this request implemented. Hiding stacks would be huge.. 

I'm not sure if this helps anyone, but it helped me.. I noticed today on Interfaces that you now have the option to hide empty Kanban Stacks. See my screenshot below - 

This for me solved my issue as my uncategorized column is empty! Don't know if it helps anyone else!
