I was thinking about how cool tags are. They truly help finding bookmarked or themed information faster. Keeping up with important issues is much easier too.
But are there any good uses for tags in system applications? Sure, there are. One particular area that springs to mind is font management.
After I have installed about 6,000 fonts on my computer I realized that it is extremely difficult for me to efficiently use them. There are no categories or bookmarks of any kind. There are not subfolders. There are no comments or descriptions. I would be willing to sort out and tag all these fonts once to be able to find the most appropriate font later.
KDE people? Anyone?
