+mind mapping has been useful to me for years now but i've been displeased with all the virtual tooling for it. i don't entirely mind doing them on pen and paper but routinely reach for them when at the computer and it feels like a phantom limb to not have software for it.
+
+i don't like how tablet/mouse oriented what i've found is...or how expensive. i also prefer text mode stuff in general bc i can focus on it better.
+
+but i have mostly been unable to imagine a good interface design for text mode mind mapping.
+
+what about a modal approach with a tiny command line?
+
+the verbs in mind mapping are:
+
+- new node
+- find node
+- new edge
+- edit node
+- pan around
+
+from normal mode:
+
+- i to create top level note in the current field
+- / to search for a node in current field
+  - select from fzf style list
+- ? to search for nodes in all fields
+- hjkl to pan around
+- HJKL to big pan around
+- c to connect to existing node (fzf search again)
+- + to zoom in, bigger boxes + less truncation
+- - to zoom out. zooming out is smaller boxes + truncated text
+- N to create a new field
+- pgdn to cycle fields L->R
+- pgup to cycle fields R->L
+
+from focused node mode:
+
+- escape to go to normal mode
+- i to create new node edged from this node
+- e to edit node (subwindow with $EDITOR embedded)
+- m to maximize node contents
+- hjkl to navigate the edges
+- enter to activate highlighted edge and go to connected node
+
+the big open question to me is placement. i want to auto suggest a place for
+new nodes (top level or not) but then leter user move around. i think it's best
+to just allow overlapping? i could program finding a place but it seems like
+too much effort.
+
+as for storage, i think anything short of sqlite would lead to a lot more complexity and work.
+
+future directions:
+
+- extracting hierchical lists from a root node
+- convert to set of markdown file
+- auto sorting of nodes to fill space
