A few items to clean up:

1. Alias imports do not show alias name in Outline view

   import java.util.regex.Pattern as Regexp

   

2. Static imports highlight "static " in editor when selected from Outline view

   import static java.util.regex.Pattern.compile

   

3. Static method imports with multiple overloads display last overload in hover and navigate to first overload
   Groovy editor:
   
   Java editor:
   

4. Static imports with an alias display improper first line in hover
   With an alias:
   
   Without an alias:
   

5. When adding imports using compiler config script, "import declarations" shows up before package in Outline view (with or without import statements, which come after the package statement)

   withConfig(configuration) {
     imports {
       star 'java.util.function'
     }
   }

   

6. When adding imports using compiler config script, import statements lack collapse region
   no implicit imports:
   
   with implicit imports:
   

7. When adding imports using compiler config script, Organize Imports (Ctrl+Shift+O) fails for source unit in default package
