Is there a way to make it look the same in Linux as in Windows? It would be great. If there is a special button/option to switch between the system and custom title bars it would be just perfect.
Theoretically Linux allows custom title bars, it can be seen in Firefox, Google Chrome, Steam, Telegram Desktop, Mailspring and some others.
