EDIT: There should be two buttons at the top of the pane: Refresh(refreshes only selected directories) and Refresh All.

Use the Windows explorer and drag&drop the folder into the MP3tag Windows while pressing Ctrl - this adds the folder to the currently loaded files and works just like a refresh for a single folder.
To reload all folders, also use drag&drop either with the selected top folder or a set of folders in the Windows Explorer.

if there was a sort of folder browser

This feature has been requested a couple of times and the best folder browser for this purpose is the display in the WIndows explorer.

feature request: directory browser on the app

This is the oldest thread that I found about a folder tree: /t/1720/1 It's from 2005. And you can see what has happened in the meantime. On the other hand: one never knows what the future will bring.
