Bunch of nits related to self. usage (which is part of our Swift style guide), and indentation.

Some other comments are bit more of importance, let me know if I can provide further information on any of those!

LGTM!

A couple of observations from a implementation / usability perspective:

• Deleting the recent bookmarks folder and then undoing the deletion doesn't reset the folder as the recent bookmarks folder location again. Do you think it should?

• At some font sizes, there is not much, if any spacing between the bookmark/folder title and the "edit" action button in the undo toast when the title is long

• When font size is large, the "Undo" button in the toast has a weird border that I don't see on other toasts with action buttons

A couple of observations from a implementation / usability perspective:

* Deleting the recent bookmarks folder and then undoing the deletion doesn't reset the folder as the recent bookmarks folder location again. Do you think it should?

* At some font sizes, there is not much, if any spacing between the bookmark/folder title and the "edit" action button in the undo toast when the title is long

Thanks Matt! Yeah definitely it should restore the recently saved folder. Theoretically if someone is pressing undo its because they've changed their mind about deletion and would like to return to the previous bookmarks state.

Also I'll take a look at the undo toast. I was using a pre-made component so I sort of assumed that it would be alright in terms of scaling.
