Request: JBRWindowTopBorder Color consistent and immersive

[rememberber]

To make FlatLaf looks consistent and immersive，like IntelliJ IDEA.
If possible, I would like to request changing the default color in JBRWindowTopBorder or adding an change option.

Thanks a lot!

Thanks for request.
At the moment I'm undecided whether this should be the default.
Especially when not using the JetBrains Runtime, all-gray dialogs are hard to recognize
because they do not have drop shadow borders.
This will change soon when FlatLaf supports custom window decorations
with native Windows 10 drop shadows on all JREs. (I'm working on this)

If you want have this in your app now, do following:

Create a file FlatLaf.properties somewhere in the resources of your app (e.g. in package com.myapp.resources) with following content:

MenuBar.background = @background

Then tell FlatLaf in which package it can find the properties file with:

FlatLaf.registerCustomDefaultsSource( "com.myapp.resources" );

Note: This must be done before setting the Laf!

@rememberber in FlatLaf 1.1 you can enable unified background with:

UIManager.put( "TitlePane.unifiedBackground", true );
