more graphical configuration

[rbuels]

Desired Features

configuration data model

• a configuration is a base configuration, plus a set of modifications to that base
• valid configuration variables are defined with metadata:
  • default value
  • validation function
  • human-readable name
  • functionality description
  • is a function callback supported for this variable?
  • if so, signature of the callback function

configuration sharing/import/export

• serialize to and from JSON, BGFF
• serialize a track configuration to a dialog with a textarea where people can copy it to their clipboard and send it to someone

configuration GUI

• take configuration data and metadata, render GUI controls for operating on it

configuration persistence

• save/restore user's configuration modifications from local storage
• during restore, if the modifications cannot be applied, just silently drop them
