TuxCards is a hierarical notebook - similar to CueCards - that enables you to organize and sort every kind of entries within a tree-structure.

TuxCards is a hierarchical notebook to enter and manage ever every kind of notes and ideas in a structured manner.
It was created out of the desire to let my own chaos of papers, notes, and post-it's vanish.

Now, regular digital notebooks do already exist in lots of different shapes, there - similar to real notebooks - I found it quite difficult to keep track of my entries and to sort them.

Through a friend I got to know CueCards; this is a really nice program that exists for Windows. Since I did use Linux almost permanently, I got the idea to write a similar tool for myself and let every Linux/Unix user share it.

With TuxCards it is possible to create as many different entries or notes as you wish. Everytime you add a new one and you think your new entry belongs to the same topic as notes you already have, then you may decide to group them and to create a kind of "folder" where you store them all together. Just the same like you would put your books and paperwork from your job together in one place and not to the garden utilities (unless you work as a gardener).

With TuxCards you have a tool at your hand to enter and manage every kind of notes and ideas in a structured manner. This makes it much more easier to find them as you are in need.

To get a picture or a feeling about what I mean, look at the images below.

Version 0.5, April 2000

I did not only want to write and sort my notes in some tool or boring program. Hence, to make the process enjoyable I've added Cactus-Support (beginning with Version 0.7). This means the user has the possibility to enable the Cactusbar to let grow some random cactuses while he/she is using TuxCards.
