Not sure how many still do active macro development or maintenance here.

Just wanted to give a heads up on my development setup.

I use VSCode with the following extension:
"dewaynejohnsonbaugh.vscodemq2",

as well as this custom setting
{
"editor.bracketPairColorization.enabled": true,
"workbench.colorCustomizations": {
"editorBracketHighlight.foreground1": "#5caeef",
"editorBracketHighlight.foreground2": "#dfb976",
"editorBracketHighlight.foreground3": "#c172d9",
"editorBracketHighlight.foreground4": "#4fb1bc",
"editorBracketHighlight.foreground5": "#97c26c",
"editorBracketHighlight.foreground6": "#abb2c0",
"editorBracketHighlight.unexpectedBracket.foreground": "#db6165"
},
}

The extension does color coding for syntax (has some errors still but a good start).
The setting does round robin color coding for brackets.

I've seen recommendations for also using color coding for indentations too:
extension: indent-rainbow

For those who do the advanced version of pulling from git to use as extension I've made some fixes and added some plugin support here:
