Microsoft updates Notepad with tabbed interface as .NETpad modernization continues

Microsoft's Notepad in Windows 11 now features a tabbed user interface, allowing users to open multiple documents in tabs instead of separate windows. This change marks a significant update after over 20 years of single-document handling. The transition to a tabbed interface has proven complex, requiring a complete redesign of the app's architecture. Developers must manage multiple document states, including names, save status, and changes, which complicates the process. Despite the challenges, work is ongoing to implement similar tab support in .NETpad. Developers are exploring solutions to address issues related to theming and styles while preparing for the new interface.
