Notepad3 is a small Windows text editor based on Notepad2 and the Scintilla component, designed to replace the built-in Notepad. It has syntax highlighting for many languages, code folding, bracket matching, bookmarks, regex find and replace, and conversion between encodings and between Windows, Unix and Mac line endings. It suits quickly opening config files, logs, CSV, G-code and input files, and a portable build runs from USB without installing. Limitation: it has no plugin system or project management like Notepad++, and it is Windows only.
