as the name says, 1/2 size buf and song window
Buf window has 25 buf slots, song window has 11 slots and uses default UI window frame so it is easily managable.

Pictured with the old UI icons, you can use the UI as is with the new icons, or copy and paste "Spells01"-"Spells07" icons from Default_Old folder into your new UI folder.


EDITED: updated the short duration buf window for TBS
