Indeed, good luck finding a singular tool that can do everything you want without intervention or compromise, at least in the no/low code realm.
It can be assumed that Blocs 4 will probably have a multitude of new features and abilities. Of course further features will come after its initial release onwards to the next major version. The following has been said vaguely.
But it does not sound like Norm is quite ready to publicly reveal much.
You can however watch and search the forum to see various tidbits. I remember screen capturing the following earlier in the year, but can no longer seem to find the actual post, perhaps removed or hidden.
So its hard to say if Blocs 4 will fulfill enough of your desried requirements until its actually released. When it does you can of course trial it and make that determination yourself, fingers crossed :–). It sounds like you are looking for specific features more so than being concerned what framework an app may/not use.
