Zanshin gives you peace of mind at the first look. However when a lot of tasks get completed, it's not possible to discern between completed (crossed out) and pending tasks and the view gets very clumsy. Maybe I'm missing the way the app was intended to be used, but I think it could be useful to have a filter to just show just what I've got to do next.
Yes, I never get around to actually implement it, but that's clearly something missing which I deem useful. I personally wouldn't have a use for it, I got the habit of just killing done tasks on a regular basis during my reviews.
Hi, I took a chance at implementing this, maybe not how originally envisioned https://invent.kde.org/pim/zanshin/-/merge_requests/3
