We've posted a Developer Preview update with some small modifications to the tool behavior on some puzzles. The changes should not be very noticeable when using the tools, but will hopefully lead to more useful solution structures. There's a new Developer Preview puzzle specially for this, called "BETA Tools Mod" to try them out on.
As usual, if you'd like to try them out, the FAQ explains how to access the preview, and please report any feedback as Developer Preview.
