CAD-KAS PDF Editor is software that helps you view and edit the contents of PDF documents. The program interface has an Explorer-based layout, so from this point of view it is user-friendly. However, the toolbar menu seems a bit overloaded.

 Sublime Text is a text editor that is an integrated software development environment (software).

The first version of the editor, released in January 2008, was adapted to work only under Windows. But starting from the second (the final version of which was released in June 2012), the program became available to users of the operating systems OS X and Linux. Thus, with the release of the second version, Sublime Text becomes cross-platform software.

In total, now 3 versions of this program have been released. The final (third) version of Sublime Text was published on September 13, 2017. Each version was different from the previous functional innovations. Moreover, developers are constantly improving their product by releasing updates.
