Is this an editor alone or does it have IDE aspects such as debugging?
Particularly interested if the latter, and a silver bullet for me would be "context" roll back, on critical failure. I wonder if there is anything like that built in, or planned?
Again if the latter, on a more fundamental level does tool methodology permit a rollback function on white screen at all, or is it integral to the WordPress interface such that white-screen would close access to any such options?
I guess I am imagining as a "best case solution" as a domain installed solution, that is wordpress aware but outside of the installation, thus bypassing failure in the WP setting that destroys the interface, though I am not bound to such an architecture.
By "context" roll back, I am thinking in terms of a built in functionality that "stepping through code" (assuming there is this functionality) would track data changes and file changes such that rollback could be automated or executed by the user, on error.
