Description of the Issue

Borders are inconsistent and have too much contrast in dark mode for my taste.

Suggestions

In short, add color settings for various borders and fix inconsistent border widths. Maybe even add settings for custom border widths.

1. Dialog - Add settings for border color and width (some prefer high contrast borders, others prefer no borders at all)
2. List box and Text box
   a. These borders are either 1.5 px wide or the control needs to shrink/grow 1 px or the controls are misaligned 0.5 px.
   b. Add setting for border color
3. Group box
   a. Add setting for border color
   b. Left align the title label (looks better when borders are invisible)
4. Buttons - Add setting for border color and width

Point 2 and 3 have the highest priority imo.

Before

After

Suggestions above refer to controls in all dialogs, not only the Preferences dialog.
