It's not just about being able to select what to download, that's a minimal part of what makes DTA so useful.

Does it allow you to manage your downloads though - like supporting multi-source downloads, pausing and re-starting, exporting/ importing lists, prioritise, re-order, limit speed, integrating with the save dialog and menus ...

DownThemAll is the one extension that might force me to abandon firefox or to stick with an ESR release and not upgrade.
