Don't feel like beaten up. This is a dreams and wishes forum and you've the right to ask what you would like to have. Some dreams will stay dreams and others will be realised.

If this history feature would have been easy to implement, it would have been implemented a long time ago. The logic is that programmers tend to choose the low hanging fruit first and the most complex features are never implemented. Sometimes new technologies can make implementing these features more feasible.

I haven't seen any tool that has implemented it properly. FDM is frequently complaining about the size of its database so every year I've to export a part of its download history.

The best way I've found for jD is to create a text file to store all my links and additional info about the downloads, before I coipy them to jD. It's searchable and it also avoids your problem with your lost Linkgrabber links.
