## [2026.4.22](https://github.com/onevcat/Prowl/releases/tag/v2026.4.22)

This release introduces Shelf, a new way to view and navigate your worktrees, along with a significant performance improvement that eliminates a source of main-thread hangs.

## New
8
+
9
+
- **Shelf view**: a new presentation mode that stacks your worktrees as books with vertical spines. Press `Cmd+Shift+Enter` or click the Shelf button in the sidebar toolbar to toggle it. Each spine shows the worktree name, branch, and tab slots; click any spine to open that book.
10
+
- **Navigation shortcuts in Shelf**: navigate between books with `Cmd+Ctrl+←` / `Cmd+Ctrl+→`, navigate between tabs with `Cmd+Ctrl+↑` / `Cmd+Ctrl+↓`, or jump directly to a specific book with `Ctrl+Option+1–9`. All bindings are rebindable in Settings → Shortcuts.
11
+
- **Command-key tab hints**: hold `Cmd` while in Shelf to swap each tab slot's icon for its `1–9` digit, making keyboard switching more discoverable.
12
+
- **Default View setting**: choose whether Prowl launches into the standard view or Shelf in Settings → General.

## Improved
15
+
16
+
- Eliminated a main-thread hang (App Hang) triggered by rapid file-change or pull-request-refresh bursts. A repeated `standardizedFileURL` comparison in the sidebar render loop was accumulating enough work to stall the UI for 3+ seconds; the result is now computed once per worktree at construction time, so the sidebar stays responsive under heavy activity.

+
18
+
## Fixed
19
+
20
+
- Shelf now correctly restores focus to the open book's terminal after SwiftUI reparenting, and properly tracks which worktrees the user has actually opened rather than showing all known worktrees.
21
+
- Toggling into Shelf from Canvas now honors the card that was focused in Canvas as the open book, rather than falling back to a default.
