Initially I tried using many β€œline” icon packs, finally settled on arcticons because of ideal:

  • thickness of the lines
  • extensive icon pack
  • opensource

Icon pack was applied through the Galaxy theme park app.

Tip

Not all the apps I have on the home screen have their specific icon in the icon pack. This was circumvented through the theme park, it allows to explicitly assign an icon to an app even if there aren’t any default ones for that app.
