Icon packs
Toolrack reads the icon packs already installed on your device — Nova, ADW and Apex-style packs all use the same format, and Toolrack understands it.
Settings › Icons › Icon pack lists what it found. Choosing one re-skins every icon that the pack provides an image for; anything the pack does not cover keeps its normal icon rather than falling back to a generic placeholder.
Icon shapes
Independently of any pack, Toolrack can mask every icon to a single shape so a mixed set of icons stops looking mixed.
Settings › Icons › Icon shape offers rounded square, square, squircle and circle.
Shapes apply to folders and bubble avatars as well as to apps, so the whole surface stays consistent.
Wallpaper dim
Toolrack’s surfaces sit over your real wallpaper with a dim laid on top, so text stays readable whatever the wallpaper is doing underneath.
Settings › General › Background dim controls how far that goes — from barely there to nearly black. It is a scrim rather than a blur: the wallpaper stays sharp, just darker.
Setting your wallpaper
Settings › General can set your wallpaper without leaving Toolrack, so choosing a wallpaper and tuning the dim that sits over it happen in the same place.
Drawer density
How tightly the App Drawer packs its icons is part of the same picture — it is covered under App drawer and search.
Page indicator
The style of the indicator under the Home grid — dots or lines — is set under Settings › Homescreen › Page indicator. See Home screen.
