[future request] Favorites toolbar settings

[cip60ckby9v6e4syst]

Here are some useful feature request suggestions.

1. Favorites toolbar: If you have set up a folder, I would like to see two options added: a tab selection to open the folder, and an option to select a new tab or an existing tab.

2. Favorites toolbar: I would like to add "vertical width" to the separator. I was very happy with the width setting!
