It would be great if you could add a bookmarks button with a drop down menu to Orion, similar to how Firefox does it:

This would serve as an alternative to the bookmarks bar and the bookmarks sidebar for accessing bookmarks. Note that this is different from the Bookmarks sidebar, it's more like the kind of menu you'd get when pressing the bookmarks button in the global menu bar on Mac. But Linux doesn't have a global menu bar, so this would provide equivalent functionality on Orion for Linux with a button built into Orion's UI.

I much prefer this style of bookmarks menu over a bookmarks bar or bookmarks sidebar, but the only major browser that allows you to access bookmarks this way (outside of MacOS) is Firefox. It would be great if Orion had this feature too!

The bookmarks button would not be enabled by default, but within Orion settings, you would be able to enable it. It would serve as an alternative to the bookmarks bar. When enabled, it would be a button on the top bar - to the left of the address bar by default, although its position could be customised.

Firefox implements it in a similar way. The bookmarks button is not enabled by default but can be added to the toolbar from "more tools > customise toolbar"
