One-choice levels collapse on their own

When a grouping level has only one entry for what you're browsing, the plugin skips it instead of making you open a folder that contains a single folder — you drop straight to the next real choice. There's nothing to configure; it happens automatically, on every path.

Worked example. Your path groups by Record Type → Album → Tracks. An artist who only ever released LPs would otherwise make you open a lone Record Type → LP folder just to reach the albums. Instead, opening that artist drops you straight onto the albums — the redundant level vanishes for that artist, while an artist with LPs and EPs still shows the Record Type choice. Several one-entry levels in a row collapse together, and a first-letter level with only one letter in play disappears the same way.
