jane (just another nasty editor) provides you with a simple-to-use editor that allows you to view and edit ASCII files easily.
This editor is a down and dirty little editor that will be right at home on your machine. There are many apps out there that can perform the same functions but don't overlook jane for use with ASCII art; she is chock full of features that can be used even if you want to keep your current favorite app.
jane will fit the bill to spruce up any text putting your creative mark, making it stand out and look cool. This is achieved by creating unique ASCII art files, inserting various special characters, modifying the available viewing schemes, among other options. It fully integrates with your machine's Windows File Explorer, keeping the process of opening files fast and efficient. It also supports drag n drop as well. There are also a ton of keyboard shortcuts to further simplify use (help files). Grab a copy of jane either in an installer or portable form and get old-school creative like back in the day.
