@zakius restoring this thread would be counter-productive, as it won't help to improve the feature. And the purpose of the feature request forum is to post ideas for improvements (by either adding new features or improving the existing ones).
Since the addition of configurable toolbars in version 2.4, the feature now exists, and users are welcome to post their ideas on improving/extending its functionality. You can do that by creating more specific follow-up requests. That's going to be more helpful than debating whether its implementation is complete or not.
We hope to see some improvements to this feature in the future, but it will take time, as there are multiple other things to take care of. 😅
