The bookmark button currently bookmarks a page and long-pressing it opens up a menu where you can choose to either do the same or open your bookmarks. Firstly, I think the menu shouldn’t be there, because it’s simply an extra action; long-pressing should immediately open your bookmarks without first opening the menu. It would also be good to have an option in the settings to reverse the functionality, so that short-pressing the bookmark button opens your bookmarks and long-pressing creates a bookmark instead. Being able to choose which bookmarks sub-folder it opens by default would also be good.
Speaking of long-press functionality, the magnifying glass button that allows you to focus the address/search bar and the home button currently do not have any long-press functionality, which seems like a waste of space. Long-pressing the magnifying glass could open up the find-in-page search, and long-pressing the home button could either open the history or downloads menu.
And lastly, on Brave desktop you can edit which shortcuts come up in the slots on your homepage. On Brave Android, it just shows you your most recent pages you’ve visited more than once in a carousel format. I think it would be better if the bookmark slots were manually editable and covered the entire page instead of having the side-scrolling carousel, or at least have an option to pick between the two display formats.
