Merge branch 'master' of github.com:encorelab/CommonKnowledge
big refactor, set up the tag specialization choosing, proposal list limiting
added Proposal Details, specialization header
smartboard: balloons now have dropshadows and glow when dragged
- single-clicking on a tag now hides unconnected contributions
- opening contributions is now done through a double-click rather than single-click
fixed: proposal list build on formatting, proposal list selected color removal and issue with tag list not rendering correctly on the first time
attempt to fix re-render issue with userState
trying a patch to prevent issues with board and tablet fighting
small UI change, and removed patch and replaced with someing a little hackier (board needs to see full saves)
