kew 4.1 adds:
- Cross-fade (both on-demand and automatic).
- More cool visualizer modes (press v).
- Auto-resume.
- Custom layouts.
More info here:
I went ahead and changed it to opt-in and it's now on main. I'm going to await what other people have to say, but likely this will be opt-in in the next release, which will be soon because there's a problem with FreeBsd.
I'm also going to add a "How to make sure kew is private" section to the readme.
EDIT: Made the release, so from 4.1.3 onward discord is opt-in.
