Many thanks to @bjansen Bastien Jansen for his improvements and
See bugs and pull requests / improvements

Of note:

• save parse trees as svg/jpg/png; right click in parse tree view (1.9)
• jump between lexer rules in different modes.
• can jump from parser grammar to lexer grammar via token rule "jump to declaration"
• Supports only IntelliJ 2016.x+ now! (Dropped 15.x etc...)

We moved to gradle. Thanks to Ivan Bryzzhin

Upgrade antlr to 4.7 (from 4.6), fix a few null-ptr exceptions see bug fixes.

New features and improvements 1.8 milestone

• Bastien Jansen added JTree parse tree structured/hierarchy view; click on the magnifying glass to highlight the input associated with a node in the structured view. Click the box with down arrow so that clicking in the input window opens up the node in the structured view. Ctrl-click now shows element in hierarchy, not just the grammar element.
• Refactorings
  • inline lexer or parser rule
  • extract lexer or parser rule
• Plugin should work in all jetbrains products now. I can confirm it works with PyCharm 4.5 and CLion 1.2 at least.
• Plugin works with 13.x, 14, 15 Intellij
• "new" icons look bad in IDEA's "dark mode" enhancement
• set text color in parse tree to "textText" property color of LookAndFeel
• grey unused rules
• Supports channels {A,B} syntax in antlr grammars now.
