[Feature Request]: Make disabled Hop lines more visible. For example: 50% transparent and "dotted/divided".

### What would you like to happen?

1) Disabled Hop lines are 50% transparent and "dotted/divided" so they are more visible. (It is very hard to see disabled Hop lines.)

2) Have an option to have the Hop lines twice as wide/thick. (less important)

### Issue Priority

Priority: 3

### Issue Component

Component: Hop Gui

Start in the Hop Gui area by locating where Hop lines are rendered and where their disabled state is determined. Compare disabled and enabled lines, then verify that disabled lines use the requested transparency and dotted/divided appearance; investigate the optional doubled width separately and confirm both behaviors visually.
