Is it possible to add custom task tags in STM32CubeIDE?
I was wondering if one could define their own task tags (special comments like the default "FIXME" or "TODO") in the IDE? The IDE is Eclipse-based, but the preferences' window is not identical. So, the guides for Eclipse, like this one (https://stackoverflow.com/questions/9586478/ide-comment-keywords) do not work.
