Yes, the new fields are great but as I discussed here https://community.mp3tag.de/t/feature-request-smallest-field-size/60179 there needs to be something half the size of Tiny. I could see the current values working with a 4k set at 150%, but I set it to 100 or 110% because I still have great vision and my 4K is 34" only 18" from my face. In this set up the Tiny field can fit 7 characters even though the tag panel only takes up 1/7th of my monitor.
Perhaps Florian should merge these two threads?
