Auto center icon is such an Eyesore, usually it will put the icon on the left then after a few updates, it suddenly auto center non name icon inside a bookmark folder!

Combine Window Emoji with Folder Icon to save space, Instead of showing a "folder icon" and an "Emoji" how about combine both into ONE?
Power user will have a lot of bookmarks and folder with more bookmark, the bookmark bar is slowly filling up and Folder Icon need a face change for more space-saving and convenience.

Bookmarking a page into a folder, still awkward to use!
Currently, there's 3 way to bookmark a site into a folder:

1 : Click the heart icon, Select drop down menu for a folder and save

2 : Click on bookmark bar, Click add site, Select the list then click save

3 : Drag the tab into a folder, click save sound easy but (this has a lot of moving bits, and sometimes you have to drag the tap across the screen)
My suggestion would be: click on the bookmark folder, then left click while on the folder drop down click save site.... Yes Just Like Chrome.
