Use Undo instead of prompting "Are you sure?"

It needs something like "Trash" implementation, rigth now files are removed as if using "rm" command on a shell prompt.

Right, so in the backend it looks like we're going to need an implementation of the XDG Trash specification [1].

Then, in the UI, we'll need a way to display the trash can, and then, specifically for this bug, an undo history.

I'm thinking the best way to handle this in Launchpad is to break this down into three bugs, one for the trash backend, one for the trash frontend, and leave this for implementing the undo history part in the UI.

I have not seem any mobile file manager with this feature, do you know any?

@Carlos Jose Mazieri
It is not important if there is a file manager out there already doing it. Google Mail on Android for example has the described undo-remove feature and it's a big usability win. The delete function stays out of the way and is still easily accessible.

iOS seems to have it too: http://socialtimes.com/files/2011/04/gmail_undo.png

In addition to what @Thibault says, it's also important to remember that this is going to be used on the desktop and tablet. I don't know for sure, but my guess is that this will probably replace Nautilus as the default file manager on the desktop some time in the future once it gets enough features. And on the desktop, undo functionality is a definite must-have.

Ok guys,

I asked because I have never seem any mobile file manager with undo, emails usually have a Trash folder, so it is easy to undo.

I will look at the implementation spec and see if it is hard to implement.

A Trash implementation is going on.

Trash is already implemented on the plugin.

The UI needs to add this, also, changing navigation to selection approach is a good idea.
