It is easy to say just need a case-sensitive partition, and sure it can be 
configurable but for example on Windows, admin rights needed for it, which is 
not available in 90% for a workstation machine in an universitiy or a general 
company.

I know the superhero operation may not possible but, i like to edit the code, i 
like to browse the code by mouse clicking easily, how possible in a limited way 
in https://elixir.bootlin.com/linux/v6.11.7/source. I like to get a well work 
IntelliSense and later Copilot AI feature.

In my use-case i do it for ARM64 embedded boards to make patches and 
modifications for my Yocto projects, it means i will run and test my kernel 
build on my target board only, which was downloaded from the remote compiler 
machine after my remote build.

As i saw that in some Youtube coding persons and cahnnels and see colleagues and 
friends, young developers more like to use IDE/GUI in Windows or MacOS for just 
coding/editing and do the basics via git, then use any SSH connection/solution 
to compile the things in remotely then test it in Qemu or a real remote 
machine/board.

In 2024 trend is for multiplatform IDEs like Eclipse, VScode and so on ... SW 
Projects also need to support the minimum possibilities to able to edit and 
manage them in multiplatform mode, otherwise this techs improvments makes no 
sense and they never take adventage of their new IDEs benefits for these 
projects in the future.
