ALE is amazingly useful even for curmudgeonly old timer Vim users. My one gripe is that I want the warnings to disappear once I begin modifying the buffer, which I have achieved. Can post the relevant part of my vimrc if desired.

I’d like to see that as well, please.

Thanks!

Wow, didn’t think you’d check back! Good to know the effort wasn’t wasted.

Yes please :)

Count me as interested!

And, ALE has LSP support.

I also use ALE, and my main reason not to switch is that I also want to run linters, and I don't want to install a separate linter plugin when I know ALE works just fine for me.

It would be interesting if ALE could integrate with nvim's LSP implementation though, although I'm not sure how that would work.
