I love the search functionality on the datasets as a whole and the new addition of the search bar on the new select tiles column layout. I would love to see this functionality added to the alter column tiles as well with the goal being to more easily find a dropped column that might need to get added back in.
There are many times we use the alter to drop noise as it doesn't break if things upstream change, but it is so hard to find columns to add back in when a request for adding a new column has come through. and we've dropped on occasion up to 100 columns.
