in the context menu I can only mark it as plain text 😕

@tschuchort: The matching rule should be something like compilationUnitContainsExactlyOneDeclarationOf(Class|Interface|Enum|Object). Could be a bug. File one if you can reproduce it

the file just seems to retain the icon I first created it with. I'm also running the very latest AS canary build

I'm also running AS Canary 5 with latest kotlin plugin. I forgot a second matching rule, the className == fileName

oh that was the issue. My class name was slightly different. Thanks!
