Add a way to undo playlist sorting, or sort by date added

[dan-dr]

Well f me. I stupidly wanted to try out the playlist sorting, and messed up a 250 songs list that wasn't sorted (just by the natural order of adding) Now there's no way to undo it. yikes. Don't think there's a date added metadata.

Any help?

An undo option is a good idea for a feature request!

Unfortunately it won't help you curently as you've already sorted it and to implement undo we'd have to store the playlist order before the sort has run to have the state to revert back to.

You are correct there isn't a date added metadata that is available on the client, so there currently isn't an option to sort by date added.

maybe i'll pull request if i have time. it was a heartbreaking experience. any clue if extensions can save persistent local data? or just for the browsing session? though mistakes of this magnitude are usually obvious right away :)

localStorage can be used to save it to the browser which should be enough to store undo states.

That would be cool if you could implement it. I'll review/merge anything you have.

This project is mostly on a backburner for me now because I don't use Rdio anymore, at least at the moment. I'll still be able to maintain the project and merge/test any features/fixes that anyone want to develop.
