- I want sbt+scalatest (the blessed build tool/test framework) to not leak memory constantly (https://olegych.github.io/blog/sbt-fork.html this is an issue I specifically run into)

- I want useful documentation when I ctrlclick into settingKeys in build.sbt

- I want Intellij to not bug out when you pass explicitly the implicit arguments required by a function that uses both context bounds and implicits

- I want intellij to always agree with the scala compiler

The first five points are fixed by using Mill

I'd like better debugging of async call stacks. Seems that'll start working better, with Java 21 and virtual threads, so looking forward to that.

And support for Scala in [web frameworks for Java].

Still on Scala 2.13, so don't know what 3.* I'd want, more than what already exist
