Love these three so much man. I especially love vikunja I wish I had looked at selfhosted project management years ago but after recently buying a house it's been incredible for orgainising everything and especially archiving everything that has happened. Anyone else use project managing tools like this? I've offloaded all of my old .txt lists of random different things into this tool.
