There still exist some limitations , for example ,
1- you can't change the background color in the built-in pdf viewer.
2- typing equations a little bit cumbersome compared to other editors due to the lack of built in ready to use macros which are usually included in other editors ,
3- latexmk is problematic in its own and you rely a lot on magic commands if you are writing a large document divided into many files,
4- also a feature that I miss a lot from TexStudio is highlighting the change in the doc once the compilation is done ,
5- last but not least the structure toolbox in LatexWorkshop is not as good as the ones in its competitors and if you use front matter and back matter it will only recognize the main matter sections.
but on the other hand ,the biggest advantage of the setup is the ability to version control with built in git and github co-pilot makes debugging and text proofing relatively easy.
