The new Navigate Files in Folder command (CmdNavigateFilesInFolder, in the Ctrl + K command palette) opens a floating window that lists the current document’s folder: subfolders and the files SumatraPDF can open, with their sizes. Enter or double-click opens a file or folder, .. or Backspace goes up a level, and Esc closes the window.

Read Aloud can now play faster or slower. Choose the speed in the new Speed submenu (in the Read Aloud menu, the toolbar drop-down and the right-click menu), or with the speed control on the playback bar. The speed is saved in the ReadAloudSpeed advanced setting.

Opening the next or previous file in the folder now loads in the background. Files that fail to open are skipped automatically, and a notification says when there are no more files. If the current document has unsaved annotations, you’re asked to save them first.
