Hi @MichaelJonker, I tested the modification with a trivial sketch (one println) and the storage space used jumped from 2150 to 2950 bytes, RAM from 182 to 272 bytes... Not a big deal if the aim was keeping the previous memory footprint.
However, the code is good and maybe a lot of people would love to use it, but maybe the best tradeoff could be providing it as an addon without touching the existing codebase (which will also let you get rid of the legacy compatibility "hacks" while being sure that existing sketch won't stop working).
Would you mind modifying the pull request to provide your functions as printFormat and printlnFormat? Also, if you could review the comments and remove all the useless ones (also from the example) before submission it would be great 😉
