+# Notes
+
+- server-client architecture via gRPC, UI separate from core
+- multi cursor based editing and slicing
+- WASM based plugins (builtin LSP & fuzzy file finder)
+
+Structure similar to codemirror:
+
+- text (ropes)
+- transactions
+  - changes
+  - invert changes (generates a revert)
+  - annotations (time changed etc)
+  - state effects
+  - additional editor state as facets
+- snapshots as an async view into current state
+- selections { anchor (nonmoving), head (moving) from/to } -> SelectionSet with a primary
+  - cursor is just a single range selection
+- markers
+  track a position inside text that synchronizes with edits
+- { doc, selection, update(), splice, changes(), facets, tabSize, identUnit, lineSeparator, changeFilter/transactionFilter to modify stuff before }
+- view (actual UI)
+- viewport(Lines) -> what's actually visible
+- extend the view via Decorations (inline styling) or Components (UI)
+    - mark / wieget / line / replace decoration
+- commands (transform state)
+- movement
+- selection extension
+- deletion
+- indentation
+- keymap (maps keys to commands)
+- history (undo tree via immutable ropes)
+  - undoes transactions via reverts
+- (collab mode)
+- gutter (line numbers, diagnostic marker, etc) -> ties into UI components
+- rangeset/span -> mappable over changes (can be a marker primitive?)
+- syntax (treesitter)
+- fold
+- selections (select mode/multiselect)
+- matchbrackets
+- closebrackets
+- special-chars (shows dots etc for specials)
+- panel (for UI: file pickers, search dialogs, etc)
+- tooltip (for UI)
+- search (regex)
+- lint (async linters)
+- lsp
+- highlight
+- stream-syntax
+- autocomplete
+- comment (gc, etc for auto commenting)
+- snippets
+- terminal mode?
+
+- plugins can contain more commands/ui abstractions to use elsewhere
+- languageData as presets for each language (syntax, indent, comment, etc)
+
+Vim stuff:
+- motions/operators/text objects
+- full visual mode
+- macros
+- jump lists
+- marks
+- yank/paste
+- conceal for markdown markers, etc
