To find a Tcl-TK application (a finished program written in Tcl-Tk), click on the top of the page Category Application (that is click on the title itself). When you'll do that, all pages that include the tag Category Application at their bottom will show up. This is the Tom Thumb system; each page has one or many rocks to trace them and when we click on the category title the rocks will all show up as if by magic and we'll know where we left them.
We might wonder about the definition of an application, but it's probably reasonable to think of an application as a program that does something that people want done.
There is an enormous number of applications written in or making use of Tcl/Tk, and most of them are somewhere on the Tcler's Wiki. If you want something in particular, you could search for a suitable keyword, such as spreadsheet, or perhaps you could use the Category system, for which the starting point is Category Category.
For more on finding things in this wiki, have a look at searching and bookmarking URLs on the Tcl'ers Wiki.

We'll refine the system eventually so that this category gets more refined as we go along.
In order to be more precise, the parent category could be called: Category Application written in Tcl-Tk) instead of simply [Category Application. In general, category names have to be precise and naming a category with one word is just a bad idea. A vague category has absolutely no use.
To refine the Category Application written in Tcl-Tk, we could have various sub-categories called for example:
* Category Spreadsheet written in Tcl-Tk
* Category Editor written in Tcl-Tk
* Category Game written in Tcl-Tk
And so on.
This involves a complex notion of sub-categorizing which is not something easily done. Perhaps some category specialist could help: AMG for example. I'm at a loss on this one.
But not necessarily for I now understand the logic of it.
I believe the parent category Category Application written in Tcl-Tk should have the Category category tag included at the bottom of the page like any category but its children categories (ex: Category Editor written in Tcl-TK should have the tag Category Application written in Tcl-Tk in the bottom.
This is how a category becomes a parent category: it only appears in category pages.
Afterwards, pages describing editors written in Tcl-Tk should only have the Category Editor written in Tcl-Tk tag.
This is I believe how a subcategory system works.
In other words, when you'll click on top of Category Category you'll find a list of all parent categories and Category Applications written in Tcl-Tk will be one of them. It is also a parent category.
Afterwards when you'll click on the title Category Application written in Tcl-Tk you'll find the list of child categories: ex: Category Editor written in Tcl-Tk Category Spreadsheet written in Tcl-Tk etc.
In other words, in order for a category to be a parent, it should only appear in the bottom of the children categories and 'Never on the page itself.
Example: Category Application written in Tcl-Tk will appear at the bottom of Category Editors written in Tcl-Tk but not in the page called Godzilla Tcl-Tk Editor. What simply will appear at the bottom of the Godzilla Tcl-Tk Editor page is the tag: Category Editor written in Tcl-Tk.
I might be mistaken however because I'm not too familiar with the subcategory system but logically this is the way the whole system should work.
However this system is way too complex and when we say complexity we delete the word intuitiveness.
At the end of the day, by wanting to be too fussy, too rigorous, we put up a complex system no one understands and therefore no one implements and we lost the initial purpose.
Bottomline is: If a system is not simple, it has no value. The more complex it is, the worse it is. By definition a system should seek simplicity.
Therefore I believe the best is not to start this subcategorizing system and to simply continue putting ONE category tag at the bottom of an application: it can be Category Editor written in Tcl-Tk for example. That's it and that's all. We'd leave the complexity and the perfection for another day. Life is too short!
So we'll have all sorts of categories.
BUT if we want to have the applications categories listed and regrouped in alphabetical order when we click on Category Category, all we'll have to do is use the following syntax: Category Application written in Tcl-Tk, Spreadsheet Category Application written in Tcl-Tk, Editor, Category Application written in Tck-Tk, Game and so on. This way they will all appear together in Category Category and they will appear in alphabetical order.
I believe this is not a perfect system but it's a pretty workable one.
