Firstly, DLT is awesome and saves me tons of time.
The only area where the Firefox DL manager does really help is the ability to branch straight to the file from the manager when it has downloaded. Often I am loading multiple files to multiple directories in the background. When the downloads are completed, it is a signal for me to go back to the DL and take action on what I have downloaded. So the download list almost becomes a mini ToDo? list (install this, unzip this, play this audio,...). It would be great to be able to run the file and delete what I have already done (much the way the FF DL manager can do).
Fantastic job.
