Please hold on with the merge until the current beta version of the intellij plugin becomes stable (next Thursday). It fixes some annoying stuff with query sync

@iancha1992 it's mostly about some annoyances, but I'd recommend to help. In the meantime - may I ask you to try it and decide if this is indeed a good change? Query Sync completely changes the behavior of IntelliJ, so it might look weird initially, but on the other hand it outperforms the legacy mode by orders of magnitude
