Drag and Drop Export
Created originally on Bitbucket by mginou (Mike Ginou)
It would be handy to be able to right-drag an Hg repository to create a non-versioned copy, or a non-versioned archive.
TortoiseSVN adds menu entries to the right-click (Middle-Click for Gnome) drag menu (So it's possible, at least in Windows). The additional options provide a quick way to export a repository.
