Tommaso's requirement, and it changes what the offer IS: a tool must sit in the
same physical position whatever you selected. Click a face, an edge or a text
and fillet is in fillet's place every time. Position becomes an address the hand
learns, and the eye stops being needed.
That kills the ordering rule this section had two commits ago. "Most-used first
for that kind of selection" is adaptive ordering, and adaptive ordering destroys
the one property that makes a spatial menu fast — worse, it destroys it exactly
for the user who has just started to learn the layout. Office 2000 shipped that
idea and withdrew it. So: NO adaptive ordering, ever, in any form.
The invariant, written to survive every future feature: every tool has exactly
one address; that address is identical in every selection type where the tool
appears; slots for inapplicable tools are left EMPTY rather than compacted; and
adding a tool never re-addresses an existing one. Empty slots are the price of
constancy and they are cheap — a compacted offer is denser and unlearnable, a
sparse one is memorised in a week. An empty slot also answers a question ("this
cannot be done to this thing") that a silently-inert tool does not.
Radial rather than a strip, reversing what I proposed last time and for a reason
that only appears once constancy is the requirement: a direction from the click
point is an absolute address that survives the offer opening anywhere on screen
and survives being clamped at a screen edge, while "third item down" does not.
Centre is a hole so the picked geometry stays visible, and it names what is
selected, so a mis-pick is caught before a verb is chosen.
Every slot carries its keyboard shortcut beside the icon and the word. This is
the graduation path and it is why power users never see a conflict: you reach
for the place, the place says "F", and one day your hand types F before the ring
finishes drawing. The offer is the mechanism by which a beginner stops needing
the offer — one interface at two speeds, no advanced mode in between.
Also here: a proposed eight-position compass map across face/edge/body/text
(create, add, remove, dress-up, repeat, transform, reference, modify) offered as
the group's first ratification, with families opening a secondary ring under the
same rule; arrow/numpad direction addressing so the spatial map works from the
keyboard; a gate question 12 that treats re-addressing an existing tool as a
breaking change to every user's muscle memory.
