Well all the UI stuff. It is super easy to add a column and change something fast with the UI when doing rapid development. But that piece is missing when developing locally. I have gone on to create 2 projects (one called local and one prod) and manually applying the changes. Would be nice to apply changes from one project to another. PocketBase here for example provides the UI locally too. That is the real selling point IMO.
Would love to hear your pain points with local development. Always looking for feedback so that we may improve your experience.
