Because Minion decides for you how wide you're allowed to make the window, I cannot snap it to fullscreen on my second monitor in portrait mode. if I try, it refuses to resize correctly then snaps back to a default position and size. That's infuriating.
I need a config file entry or something to fix it and allow arbitrary window size. Yes, that means there might be elements that get hidden or cut off when it's like that, let me worry about that for myself.
For a developer, trying to know every user's use case and predict what their needs are would be pure madness, and without knowing that, you don't have the information to make decisions like this better than the user themselves can. So don't.
