Description

Is it possible to get diagnostics when text is edited, like with a debounce/delay so its not overwhelming?

Right now I have to save in order to see them - which is more of a problem than it may seem since old errors lurk around and pollute the screen

Done means diagnostics refresh after editing with a delay that avoids overwhelming updates and no longer requires saving.
