TODO

Link to jump into minibar
Start with initial grammar, startcat, ast
Compatibility with grammars with dependent category types
Clicking on tokens to select tree node
Use local caching
Enter string/float/int literals
UI issue with DisambPhrasebookEng
more prominence to Disamb-linearizations
ambiguity: (optionally) parse all the resulting linearizations/variants and point out those which are ambiguous
try to retain subtree when replacing node
add undo/redo (or back/forward) navigation
structure fridge magnets some more (eg newline before the magnet whose first letter is different)
The formal-looking funs and cats are not linked/aligned to the linearizations. Maybe a possible UI could be where the user is clicking on the linearization (in a chosen language) and the tree is drawn under it (from top to bottom, not from left to right as currently). So that the alignment of words to functions is always explicit. But maybe this is not doable.
