Juraj:
how?
I don't know the exact technical details, but it is stored under this folder:
I believe it is a database. I haven't figured out how to take a look at the data in there.
The data is associated with a given sketch path. It is the same system that stores the "workbench layout" (e.g., whether the Serial Monitor view is open) for a given sketch.
Yeah, unfortunately the system doesn't always work as I expect it to. I have never managed to figure out exactly how it is supposed to work. My opinion is that the developers got a bit too "clever" when writing the code:

### Describe the request
Emulate the tried and true reliable behavior of Ardu… ino IDE 1.x regarding board and port selection.
- Always use the board the user selected.
- Always use the custom board options the user selected.
- Always use the port the user selected. **\***
🙂 Users will not be subjected to confusion or frustration caused by the IDE automatically selecting an incorrect board and port
🙂 Removal of this highly complex system will make the Arduino IDE 2.x code base easier to maintain and develop
**\*** There is one exception to this rule: when uploading to a board that has native USB capabilities, the CDC serial port of the board enumerates at the start and end of the upload. Most often, the port will have the same name at the end of the upload as at the start, but it is possible that the operating system will assign it a different name, and that final port should be selected in the IDE after the completion of the upload. Arduino CLI already handles the port switch at the start of the upload, so it should also be responsible for determining the port name at the completion of the upload and providing Arduino IDE with that information (https://github.com/arduino/arduino-cli/issues/2245).
### Describe the current behavior
Arduino IDE 2.x attempts to automatically select the appropriate board and port for the user.
The concept is certainly commendable, and when it works correctly it is convenient. However, when it does not work correctly, it can cause confusion to less experienced users who won't notice that the automatic board or port selection is incorrect, or frustration to users who do notice and must fight the automated system to attain the correct selection.

This is not a matter of a regression of a system that worked at one time, but rather an highly complex system that never worked correctly from the start of the 3 year development of the code base. So there is no reason to think it can be fixed as a simple bug.
