A few people have moaned about the editor. I find it quite adequate in the main, and use tier 1. I have no need or desire for autocomplete as I consider it annoying and generally unhelpful. If I put do, I do not want the editor to try to put loop at the end it can cause issues when editing code also. I can end up spending more time deleting the erroneous extras it introduces than I save by it actually being correct.
I do miss the label list from DB though, and I have tried breaking my program into smaller parts but find it far less useful generally.
Other than that AppGameKit is a far better beast for 2D games work imo.
