Espressif Eclipse not behaving like Eclipse

[ignisuti]

I'm a huge fan of Eclipse, but so far my experience with the Espressif Eclipse IDE has not been good. There are several features I really liked that don't appear to be working. Please help me understand if the issues I'm seeing are fixable.

Issue 1:
CTRL & ~ - No longer toggles between C and H files.

Issue 2:
Hyperlinking - ALL hyperlinking seems to be non-existent. It's not just clicking on a header file and getting taken to that file. I can't even click on a variable to taken to the declaration.
Ideally, I want to get the indexing functional so that when I click on something like #include "nvs_flash.h", I jump to the file in the ESP-IDF.

Issue 3:
#define coloring - If a section of code is blocked out using a #define, Eclipse should change the color of that section. It is not doing this.

If you continue facing challenges, consider using Visual Studio Code with the ESP-IDF extension.

I've already considered it and think I'd rather use Eclipse as-is than make the switch to VS Code.
Surely there will be ways to fix these issues, right?

I guess my first question should be... Is this the Espressif variant of Eclipse that's causing the issues?
If so, I could always use stock Eclipse.

Correction... With Issue 1, it was CTRL + Tab that used to toggle between .c and .h files.
What would cause this functionality to stop working? I have indexing enabled now, but it's still not functioning.

No one else has had these issues or resolved any of these issues...?
