Issues that prevent me from switching to LightTable
View My LightTable problems.md

Absolute blockers:

  • Vim#13 - * search state
  • Vim#43 - no auto-repeat (connected to Vim#8 - see below)
  • Vim#44 - invisible cursor (there's a workaround)
  • bad color scheme (connected to issue above)

Problems that prevent me from using special LightTable features

  • JS#10 (I've made [a fix][1])
