OMMT 3.0.4

• Fixed a crash when pressing Enter with an incomplete Minecraft sound search. Search text is now separate from the selected sound, and applying an unselected sound reports a message safely.
• Replaced the other Minecraft sound picker with a separate, non-dockable window. Search appears at the top, with an alphabetical, vertically scrollable sound list below. Search results are ranked by match quality; an empty search shows the complete catalog.
• Added a ▶ preview button beside each sound and a Stop button. Starting another preview stops the previous sound, including long music tracks. Closing the sound window or editor also stops its preview.
• Removed the 200-result limit. Only visible sound rows are rendered, and searches are recalculated only when the query changes.
• Added a per-song part display selector beside Settings: Automatic, All parts, or By instrument. NBS instrument groups now survive closing and reopening the editor.
• Saved the display mode and imported NBS hierarchy in .ommt projects. Instrument grouping changes presentation only; note data and part identities are retained. Parts containing several instruments are grouped by their most frequent instrument.
