Is it possible to have tabs that you could rename in the Package/Filename? example:
[ ] Package00 [ ] Package01 [ ] Package02...

Where [ ] is a checkbox to; enable [x], or disable [ ], downloads from that section.

and users can sort their packages/files/links into these different tabs. Example:
[ ] Movies [ ] Porn [ ] Applications [ ] eBooks [ ] Whatever

A tabbed package/filename section would prevent us from having a massive link list with hundreds of packages and thousands of filenames...

You can already do that in jD by using the packages themselves.

You can :-
- rename your packages as you wish;
- move links from one package to the other;
- disable entire packages or links.

A recursive subpackage feature would of course be welcome.

I would prefer one more level, so I can cateragorize the packages with associated files better. I keep completed packages around so I know what i've downloaded already...
