Kile

Kile is a sophisticated program that will help you write complex, A-level academic papers and theses, all formatted to the highest standards. The tool's predefined templates and document wizards enable access to modern typesetting methods, all in a matter of seconds.

Kile is a complex ecosystem that offers access to plenty of editing features and a lot of customizations for you to have the best user experience. The program is pretty large in size, and it is a little bit challenging to finalize the initial setup (although it is mandatory for optimal performance). However, once you have finished setting it up, you are good to go, and you can use the tool for years. Kile is the kind of program you will use for a very, very long time. Why? Because it's solid, really complex, smart, and sustainable.

After installation, you will be prompted with a wizard checker that will analyze your system and tell whether or not you are ready for processing LaTeX files. The system checker will let you know if additional elements need to be configured and/or installed. If you don't have a document preview optimally configured, it will suggest installing Okular, a LateX, TeX, and other types of document formats reader.

Kile allows writing and editing LaTeX and TeX documents elegantly. We know how difficult it is to write using both of these text formatting systems. It requires patience and a knowledgeable individual. Using the Kile editor, besides permanent access to a variety of templates and pre-defined markups, you also have four different preview methods available.

The tool allows you to quickly preview any given modifications. You can do a fast preview by selection mode, where you have a focal perspective over the selected portion, an environmental preview (mainly used for mathematical purposes), a subdocument preview that is used for compiling smaller pieces of the project, and lastly, you can do a quick preview on a particular mathgroup set you are editing.

Because both LaTeX and TeX are typesetting systems used mainly for writing scientific content and technical documentation/presentations, you need a good, stable program, with a solid system-architecture. Kile is a robust editor with a lot of valuable features.

It supports insertions, citations, flexible compilation, easy and quick document previews, tags and symbol insertions, advanced editing commands, and last but not least, it gives users access to an extensive manual with instructions and detailed explanations for all the processes; that guide can be found here.
