Or at least a way to filter tiles out of the planner, I don't want the bots spending hours removing tiles that I actually need

I believe that it is unlikely, that your feature request can be implemented. As far as I have seen, Factorio doesn't provide in its API a way to add "holes" in the planner.

I tried to use a deconstruction planner (the regular one) filtered to all applicable tile types (landfill-concrete-etc) (reverse deconstruction with shift+left click drag) Immediately after the sensible deconstruction to cancel the removal of tiles, but the mod stops deconstruction and I cannot queue a new sensible deconstruction order for a while. I believe if that can be somehow fixed the mod would become much more useable.

Thank you for the comment. It is correct, that currently it's not possible to cancel a running deconstruction - it runs until it is completed or hits a dead-end. I have added a note about this in the list of missing features. My intention with this mod was to create long-running deconstruction tasks, so this missing usability feature was not on my mind, since I don't use it in that way.
