This would bite me in the ass because I often ignore these kinds of warnings in VSCode (SFDX for VSC is kinda crap, warns you about nonissues, and often doesn't correctly identify the problem).
Confusable characters get a little yellow box which is different from the squiggly underlines most linters and stuff use which at least makes it a bit more recogniseable.
Personally I can't stand having underlines all over my code, so I'll usually just "fix" the non-issue if possible, or otherwise just disable whatever the warning is entirely.
I love that look, ugh. The inline errors are much more visually appealing vs the usual squiggly underline
I might need to look at vscodium since I'm not too keen on having more microsoft telemetry on my desktop. Been using Atom for personal projects thus far.
