@pahen

Thank you for your PR ! 🎉🎉🎉

We track the things which maybe can be fixed with theme API supports in the future here.

Perfect! 🕺

The "Text selection color" should work already. Can you provide a screenshot where it doesn't work @ajitid? And what version of VSCode are you running?

[pahen]

Correct. It was added after 1.12.2 was released. Should work in insiders build.

[pahen]

The same is valid for "Allow theming of parameter hints". Should work in insiders build.

[ajitid]

Okay, removed all of my comments. Thanks!

I moved out the relevant stuff into own issues so I think we can close this now @teabyii
