some while back I started a spreadsheet to list the things I want in an IDE - https://docs.google.com/spreadsheets/d/1WxTDBB3DnJ8MVRes5bUBJCjP14Dy6U-95kc01xndWTU/edit#gid=0 not exhaustive. and quite a few things in your article are not there , e.g. structured editing. maybe bc they seemed too obvious. to a beginner ofc full list would be useful
