Hey guys, I am one of the authors of the vscode extension. I would say that the changes between the 2 are numerous and so cumbersome to enumerate, so I think I will skip that for now.
What I would suggest to keep this discussion constructive is to go to our GitHub repo (GitHub - fortran-lang/vscode-fortran-support: Fortran language support for Visual Studio Code) and scroll through the existing issues and see if you have any ideas on how to improve things (feature wise). You also file new Issues features/bugs just please make sure to not spam us with duplicates or questions (questions can be posted on Discourse with the help vscode tag).
To be clear I don’t expect anyone here to contribute code to resolve any of the existing Issues, but if you really want to donate your time I would be more than glad to onboard you in the project, discuss solutions and review your code.
As I mentioned earlier this week in another post here on Discourse
There is already a half-finished Pull-Request on GitHub that would dramatically improve Python integration with Modern Fortran, especially on Windows
If you feel like helping by brainstorming please be respectful, concise, look through existing and closed Issues and provide good descriptions your requests.
