Size of “repeats & jumps” markings

“Repeats & Jumps” markings like the Sign, the Coda, “DS al Coda”, etc are too small for me. I can increase the point-size manually by adjusting it’s Properties each time, but I can’t find where there size is adjustable under Format->Style. It would be great to adjust this once in a saved Style so all my lead-sheets would benefit.

Bonus question: I select grace-notes from their pallet and apply them fine. But though the pallet symbol shows a slur connecting to the destination note, my score never shows the slur either on-screen or in the printout. I have to put each slur in manually, correct?

I’m running 4.3.2 on Windows. Thanks….
