## Available startup options
|Options|Description|Default|

|target | |"editor"|
|initial.grammar|Initial grammar URL, e.g. `"http://localhost:41296/grammars/Foods.pgf"`|-|
|initial.startcat|Initial startcat|-|
|initial.languages|Initial linearisation languages, e.g. `["Eng","Swe","Mlt"]`|-|

## Example usage

## TODO
- Wrap a subtree
- Compatibility with grammars with dependent category types
- Clicking on tokens to select tree node
- try to retain subtree when replacing node
- Use local caching
- Clipboard of trees
- Usage of printnames
- Enter string/float/int literals
- more prominence to Disamb-linearizations
- ambiguity: (optionally) parse all the resulting linearizations/variants and point out those which are ambiguous
- add undo/redo (or back/forward) navigation
- structure fridge magnets some more (eg newline before the magnet whose first letter is different)
