You can still try CLion (the trial version) and see if it’s what you’re after. You don’t have to use it but IMHO complaining so much about there not being a decent IDE without even trying the proprietary ones isn’t very fruitful. CLion is what Borland was back in the 90s.
The thing is even if CLion does what i want (TBH i doubt it[0]), i wouldn't use it anyway so i don't see a reason to spend money on it. Note that my issue wasn't so much that it was proprietary (though it is an issue[0]) but that it requires an internet connection to function.
After all i still have and can use Borland C++ 5, Delphi 2 and C++ Builder 1 to this day without requiring any sort of connection or having Borland's permission to use the software i bought. I can't do the same with CLion.
[0] CLion relies a lot more than Borland on external tools like GCC, CMake, GDB, etc meaning that not only it most likely does not provide all the integrated functionality i mentioned but there is also a very high chance it will stop working at some point as its dependencies are changing so you do need to rely on JetBrains to keep it up to date without having access to the source code.
