OutWiker - the tree notes organizer


OutWiker is designed to store notes in a tree. Such programs are called "outliner", personal wiki, or tree-like editors. OutWiker's main difference from the other similar programs is keeping the tree of notes in the form of directories on disk, and encouraging changing the base by external sources and programs.

Also any number of files can be attached to the page. OutWiker can contain pages of different types, currently supports three types of pages: plain text, HTML pages and wiki pages. You can add Markdown page support with Markdown plug-in.

The program uses some sets of free icons taken from sites famfamfam.com, yusukekamiyamane.com and fatcow.com. Many thanks to the authors of those sites.

OutWiker distributed with source code under the GPL 3.

May it be better to make the program keep notes in one file?

Keeping notes in a tree - the main feature, for which the program was developed. This does not mean that someday I will not add the option for choosing ways of storing your notes, but this will not happen in the near future.

Will there be a visual editor for the pages?

There are some thoughts to make a separate page type format RichTextFormat with the visual editor. Please do not exclude the possibility that there will be a visual editor for HTML-pages. But still I can't talk about dates.

How to install plugins
