# TODO

- [ ] **MAJOR** Implement configuration manager:
  - configuration is a set of signals (that can be organized in group and subgroup) that are used to configure a system or a sub system
  - with configuration manager user should be able to:
    - Define and manage configuration sets: delete (keep server side copy of deleted config), create (specifying default to parameters, mandatory, optional etc), edit (with versioning git style) and compare set
      - user can fork an existing config instance to create a new one
      - user can compare two instances: show unified diff or side by side diff
      - etc...
    - Create, delete (keep server cache), edit (git style versioning) and compare configuration instances: meaning set actual value to a configuration set
      - user can fork an existing config instance to create a new one
      - user can compare two instances: show unified diff or side by side diff
      - etc...
    - user can apply and save configuration instances
    - in logic editor and control loop add nodes to read/write/create/apply config instances
- [ ] Improve UX:
  - [x] Synthetic editor:
    - [x] color code the node link by type
    - [x] hover on a block in error should show the reason
    - [x] add proper array functionality
    - [x] add shortcut to add Signals (S) and nodes (N) with HUD
  - [ ] Panels:
    - [x] in view mode the widgets should have no border/bg but blend with background
    - [ ] add widgets such as toggle switch, table and other industrial hmi widgets
- [ ] Implement git style versioning for: synthetic variable, panels, control logic:
  - possibility to fork any version
  - click to view the version
  - possibility to view graphical diff between versions (side by side or unified diff)
  - simple slick versioning pane:
    - vertical tree like
    - each version represented by a circle
    - active (the one currently view/edited) version has circle bigger then rest
    - selected (the one that will be executed/showed by user) version has circle full, not active only border
    - unsaved / new version appear with connection line dashed
- [ ] Implement admin pane: create / manage groups, set users permits, manage auditors etc
- [ ] Implement new datasources:
  - [ ] Finalize alarm service
  - [ ] modbus tcp
  - [ ] scpi tcp
  - [ ] udp? other?
- [ ] **MAJOR** Implement proper distributed server side nodes to balance load and have redundancy (if a node is not available anymore all its clients migrate seamelessly to another)
