User:Johan G/Todo and fixme template sandbox

I'm not sure they are an all too good idea, at least not in articles meant as user documentation, but I have sometimes pondered these.

Usage

The templates would automatically categorize the articles.

As for mockups how would something like this look:

{{todo|To do|Alternative category |nocat=}}
{{fixme|To fix|Alternative category |nocat=}}

Parameters

All parameters optional.

To do/To fix

Comment on what needs to be done.

Alternative category

Alternative category to add to the pages with the templates.

nocat

If not empty the template will not add a category to a page with the template.

Example

{{todo|To do}}

{{fixme|To fix}}

#TODO To do

#FIXME To fix
