Having had many a scuffle with macros et al in high school in the late 90s, which can only be described as “I made it the way I wanted it perfectly last night, now it is a dog’s breakfast!!!” A bit like “the dog ate my homework” to the teachers.
Once bitten, twice shy as it always is and thus ever since, I have preferred to do documentation, presentations even websites etc. in ways that I can completely control and cannot be tampered with by compatibility issues, font deficiencies and default settings whims.
