The Jade 2025 release focuses on modernising the developer experience and helping you build faster, smarter, and more scalable applications.
It would be beneficial to have a horizontal scrollbar in the class, method and property panes within the class browser, especially in the classes pane.
I find it useful to have the classes pane arranged vertically down the entire left-hand side of the IDE, and classes that are several layers into a class hierarchy and/or have long names can be cut off, so the ability to scroll horizontally, instead of having to widen the pane, would be useful.
