The nest's machine and its Nest Info fields were the last edits only the
fingerprint safety net could catch (and it misses most of them). Machine
is now one step, together with the support grid and cut-off settings the
machine brings. Nest Info is one step for what Undo can put back (units,
material, thickness, customer, notes and plate defaults); the name,
status, author and creation date stay as they are through Undo, so an
edit of only those records nothing.
The sheet strip only shows Auto Nest proposals; what it shows is
committed through Auto Nest, which is already recorded.

Drawing changes were unrecorded, so Undo skipped them or lumped them
into an anonymous "Change". Each is now one labelled step: Import
Drawings, Shape Library (menu and panel button), Drawing Library (what
the dialog added or re-quantified), Save to Drawing Library (the nest
keeps the drawing's new library link), Edit Drawings in the converter,
Drawing Properties, Delete Drawing and Clean Unused Drawings. Dropping a
drawing on a plate was already recorded as Add Part and is now tested.
The converter can change live programs while it loads, even when it is
cancelled; a cancel that did so now rolls the nest back to before the
converter opened instead of leaving those edits unrecorded.
Deleting a drawing threw when removing its parts emptied the trailing
plates, because the plate manager drops trailing empty plates while the
loop walked the live plate list; it walks a copy now.

Cutting edits were unrecorded, so Undo skipped them or folded them into
an anonymous "Change". Each is now one labelled step: Add Cut-Off, Move
Cut-Off (one step per drag), Automatic Cut-Offs, Auto Sequence (current
plate or all plates, only when the order changed), Set Sequence (per
click), Sequence by Path (the whole tool session; Backspace and Ctrl+Z
inside it still take back one line), Place Lead-In, Remove Lead-Ins (the
tool's menu, the plate and the nest commands), Cutting Parameters (an
edited lead-in panel when the tool closes), Plan Cutting and Clear
Lead-ins and Cut-offs.
Plan Cutting stages scrap cut-offs on the live plates before it plans,
so its scope opens with the staging and records only when the plan is
applied; closing without applying records nothing. Clearing applied work
is its own step and no longer warns that it cannot be undone.
Opening the lead-in tool used to give a plate without parameters the
defaults straight away; the plate now takes the tool's parameters with
its first lead-in, so opening and closing the tool changes nothing.
Undo no longer waits while the tool has a part picked: it ends the tool.

Plate and clamp changes went unrecorded, so Undo skipped them or lumped
them into an anonymous "Change". Each is now one labelled step: Edit
Plate (only on OK), Rotate Plate, Resize Plate, Set Nest Default Plate,
Clamps and Support Grid (applying to the nest; saving machine defaults
stays outside the history), Remove Clamp / Put Clamp Back from the
plate's clamp menu, and Add/Move/Delete Clamp in Edit Clamps.
Edit Plate used to copy an empty plate's settings into the nest defaults
even when the dialog was cancelled; that now happens only on OK, so a
cancelled dialog changes nothing.

Placement edits were only caught by the fingerprint safety net, so they
undid as an anonymous "Change" or folded into the next edit. Each now
records one labelled step: Fill (at the commit, so a stopped fill that
keeps nothing records nothing), Fill Area, Pattern Tile, Auto Nest (from
the kept proposal only; Make Nests tabs too), Clear Nest, Remove Empty
Plates and Center Parts. Clear Nest no longer warns that it cannot be
undone.
Pattern Tile onto a new plate created a plate beside the empty sentinel,
which the plate manager dropped at once, so the pattern landed on a
detached plate; it now fills the sentinel.
The undo tests share one harness that compares a text description of the
nest before an edit and after Undo.
