Ok for me, even closing. That list really makes me sad, but unfortunately even diving into one of the more complex pull requests there takes more time than I have currently available, and I don't see that changing any time soon.
There is a lot on the list I would like to see finished, but it doesn't help keeping the PRs open and the code getting stale. But maybe the PRs can be labeled something, like unfinished, to make it easier to find them again to take up the work.
Regarding my own pull requests there are only two, and I would really like to have "Removable tags" fixed, as it would fix an important shortcoming in current Picard.
But given the fact I haven't managed to do this for over a year now is not a good sign. So if somebody wants to take on where I left feel free to do so.
