New in the SumatraPDF pre-release builds: Save and restore tab groups You can save the current set of open tabs as a named group and restore it later with Save Tab Group (CmdTabGroupSave) and Restore Tab Group in the Ctrl + k command palette. Saved groups are stored in the TabGroups advanced setting (#4402). Highlight matches in filtered Table of Contents When you filter the Table of Contents / bookmarks tree, the matching text is highlighted in each entry.
