NoteTab Pro is without a doubt one of the most feature laden versatile programs on the market today that any user can benefit from. In over 20 years of I am still constantly finding more features and everday uses of the program. It is the program that I open first when I start my computer in the morning and the last one I close when logging off in the evening

NoteTab Pro (and free) is one of the best rich text and html editors I have, or have ever used. It is a tab oriented text editor. It colors html tags with different colors for links and text. NoteTab makes use of a system called clips, which are written in plain text readable clipcode. A user can edit the built in and downloadable clips or create their own. I use my own html clip to load any tag, attribute, element or modification I want to an html page. The current version ships with an html 5 clip that has all of the W3C approved tags and attributes. Any number of tabs can be opened as new pages, or saved works in already in use. You can drag and drop a text or html file onto NoteTab (even on an open tab) and it will open as a new tab! The tabs line up along the top and have left and right arrows on one side to scroll through them. Or, the open tabs can be stacked in long horizontal rows if you prefer. The search function can either search the tab you are in, or all open tabs for matching words, terms, codes, or regular expressions. There is also a search disk function that searches any folders you list, including or excluding sub-directories. Matching documents can be selected to open in separate tabs. There is a search and replace box for the open tabs that accepts both plain text and regular expressions. There are two web browser buttons on a toolbar to open your current document in one of two configurable web browsers (if they are installed). NoteTab does outlines, plain text, rich text, unicode and html, as well as php and other code languages that are not binary encoded. If another editor modifies the content of a tab that is open in NoteTab, a box pops up asking if you want to refresh and load the new content.
