v0.10.2.0 - Select Box, Group Editor, Reactions Graph

• Selection Box / Ruler
• Inspect: one card for the whole selection — counts, sums, averages, ranges

• Group edit: values, sliders, material — applied to every selected object

• Material: dropdown picker in the card

• Histograms per property: click a bar = narrow the group, Shift+click = exclude

• Layer as enum

• keybinds reassignable for the group

• Flags show honest shares; numbers in K/M/G/T

• Ctrl+A select all

• Delete key removes the selection

• The card remembers folded tags

• Palette: '1 row' mode with paging

• Reactions: all reactions as a live graph — materials are nodes, reactions are links

• Force auto-layout with a tuner; the arrangement is saved

• White = direct parts, gray = catalyst ties; hover unfolds dense pairs

• Click a material on the map to inspect it; unused materials filter

• New reaction opens as a card; short how-to on first open
