Being able to add and edit data in the 8base UI is a huge win when creating an app, since you can easily create data when your app is at an early stage and is read-only. It would be even better with a few additions:
Being able to filter tables by null. Right now, you can filter by associated table fields, which is awesome in itself, but you can’t filter for null references. What is possible is sorting by the associated table’s id (or any field), so you can sort the null items first.
Seeing associated table data in the row of a table is another huge advantage. The next step would being able to click on those fields and have it jump to that row in the table. Currently, you need to remember the name, then go to that table and find it.
