Could you please consider adding the following:

1. Ability to snap TomTom arrow to click target. Currently changing UI scale puts the arrow in a different location as it has nothing to snap to.
2. Add ability to change font on click target + font size

Meddling with the tomtom arrow might be a pain, just because it is a shared thing that my stealing the focus for wouldn't be ideal. I'll take a look at tomtom and see whether it has any facilities for this built in, which would make it simpler.

Changing font and font size... probably doable. I'd need to see if I have any spacing which assumes pixel sizes of a line of text rather than anchoring.
