Buttercup has come to an end - an explanation and a thank you

The Buttercup project is coming to an end

I've spent a long time debating this decision, but it's one that I need to make, since the project has all but stagnated. You've probably noticed or suspected this, if you've come into contact with any of Buttercup's repositories recently. While many of you have helpfully been reporting issues, there have been few responses (especially from myself) and even fewer PRs addressing them.

I wouldn't call this burn-out, first and foremost.. I honestly feel fine and excited by the prospect of developing OSS even. That being said, I do feel substantial relief at the thought of putting Buttercup onto potentially permanent hiatus. The project is enormous in scope - it would be for a small team of developers, let alone a single dev working full time who lacks both the energy and motivation to support the project. I've tried getting more serious help on board too, though since Sallar (the other co-founder) left it's honestly been just myself holding the fort. It's a passion
