I never really understood the use case for things like this. You can get the logs with docker-compose logs and you can see what's running with docker ps. So I'm not really sure why you'd need this.
I believe they're talking about how abstractions tend to make people more productive. Operative term being "tend to", because I personally wouldn't use this tool either, but to each their own.
I mean, with all due respect, but if you cannot see any reason for this to exist, even given the explainer in the readme, then it's clearly not for you. But just because it's not for you doesn't mean I can't be for anyone.
I read that and even downloaded it and tried it, but like the other commenter said, it's just not for me. I don't see any value added compared to just using the docker-compose and docker commands.
I love this developer's other tool, lazygit, which I use every day. And I can see this one is similar quality, even though it doesn't appeal to me personally. Glad it helps some people out though.
It lets you quickly tab back and forth between different containers and keeps everything on one screen. You could accomplish the same thing by fiddling in tmux, but this has it all ready to go in one command.
