Trello.

First it was scraps of paper with multi-item lists of various nature - from things fixed in the next release, to known issues, to feature requests, to random stuff with nothing in common. Then I moved to using Inkscape and it worked well, but moving items between the lists and archiving them was a hassle. There were also no search and generally it's just a vector editor, so it was a stop-gap measure. Then I thought of writing my own system, even drafted the spec only to realize that I was looking at replicating Trello. So Trello it was. It's not perfect, I would change few things about the UI and certainly re-style it, but it is surprisingly good as is.

That said I still use scraps of paper as it's the fastest option of them all.
