NoteTab Light remains one of the most widely used Notepad replacements, mostly because it compiles an impressive number of features. The simple tabbed interface allows users to search files, strip HTML tags and format text as fast as their proficiency goes along.
Macros, on the other hand, may further increase work speed. The free version is also able to capture clipboard text, perform in-text calculations and create and reuse text snippets.
You may indeed lose some important features that come for free with other similar software, but you get in return HTML5 and CSS3 support and code libraries and web page templates.
