Expand the English README into a practical guide covering installation, accounts, queue controls, automation, history, backups, updates, troubleshooting, and development. Add four sanitized workflow screenshots and enforce their exact public manifest. Restore the animated Backup submenu outside its parent menu, keep expanded account groups naturally sized in the scrolling Accounts list, and strengthen Electron UI regression exit codes.
Add live English and German interface switching, animated navigation and history controls, improved update changelogs, remembered upload folders, reliable repeated hot reloads, and refreshed public documentation.
