Immediately when I make a change to a global library file / element, I get a popup at lower right that suggests publishing changes or dismissing. This is very intrusive and annoying. I suggest moving it to the top toolbar or somewhere else out of the way, so it creates less friction and distraction in the user experience. Further, when the notification is dismissed, it’s a hassle to later navigate to the assets panel to review and publish changes. That hassle would also be removed by the idea of moving the popup notice to a button or something in the top bar or elsewhere.
TL;DR: Move the “publish” option to a less intrusive yet also more quickly accessible location in the UI.
