CANVAS TOOLS (18)

KNOWLEDGE GRAPH

Every object is a Mnem — atomic, linkable, typed. Connect Mnems with Threads using 17 typed relationship kinds: references · inspiredBy · continues · about · partOf · relatedTo · supports · extends · contradicts · summarizes · dependsOn · implements · causes · belongsTo · derivedFrom · createdBy · duplicates

6 OBJECT KINDS: Thought · Idea · Task · Person · Reference · Daily

Link inline with [[object name]] syntax or through typed field references (Capacities-style).

11 LENSES — same data, different projections, single source:

Canvas · Graph · Journal · Search · Timeline · Gallery · Table · Tasks · Collections · Research · Recent

LIBRARY

Grid and list views. Sidebar: All Works, Recents, Favorites. Thumbnail previews, multi-select, bulk actions, date grouping, sort by name or date.
