Still waiting on my favorite jetbrains feature—show type of selected expression. Probably the single most used IDE feature in my toolbox when I used scala.

It looks like this is blocked upstream by the language server protocol not passing the current selection for hover requests [0].

FWIW, this should be relatively easy to implement. Looking at all the pieces which implement https://github.com/rust-analyzer/rust-analyzer/blob/master/d... should given enough knowledge to do this.

At least in Emacs, it shows the type as a tooltip if I hover over the closing paren of a function call.

Works in VSCode too, not sure what specifically their problem is.

With inline hints you can get something somewhat similar, although they can get very annoying with complex types. But extremely useful in long method chains.
