Reflections on vibecoding ticket.el

It has now been a month since I started playing with Claude Code “for real” and by now I’ve mostly switched to Codex CLI: it is much snappier—who would imagine that a “Rewrite in Rust” would make things tangibly faster—and the answers feel more to-the-point than Claude’s to me.

SumatraPDF new features: April 4, 2026

New in the SumatraPDF pre-release builds: Bake PDF File New Bake PDF File command (CmdPdfBake) in the Ctrl + k command palette turns interactive form fields and annotations into static page content and saves the result as a new PDF, which then opens. Show PDF Outline New Show PDF Outline command (CmdShowPdfOutline) in the command palette shows the document’s outline (table of contents) as text in a window. Tab Groups menu Saving and restoring tab groups now has its own Tab Groups submenu (in the Favorites menu) with Save Tab Group and Restore Tab Group. Both are also in the tab right-click menu. There is also a window for managing saved groups (#4402). Screenshots include open menus Take Screenshot also captures open menus as separate windows you can pick. Menu bar improvements with tabs The custom menu bar shown when tabs are in the title bar works more like a normal menu bar, and toggling the menu bar is more reliable (#5442, #549). More: changes from April 4, 2026 and the full changelog.
