# Todo
|

|
||||
## Todo Now
|
||||
* Remove port number magic numbers in GraphAlgorithms.hs.
|
||||
* Consider removing LikeApplyNode and CaseNode, or their embedded versions.
|
||||
* Fix embedded lambdas missing their enclosures.
|
||||
* Add command line flags for color style, embedding, and whether to draw arrowheads.
|
||||
* Add wiki pages discussing: Why a visual language?, History of Glance, How to contribute, Code guide [code style, ...], etc..
|
||||
|
||||
## Todo Later
