The top padding on the dock is auto generated based on the vertical grid, but I can still tweak the bottom padding some. Send over a screenshot so I can compare to P6 and find a happy median.Good job! Black folder background now works on Pixel4a.
For the records:
pixel4a SP1A.211105.002
magisk 23.0
substratum lite overlay helper 0.5.20
pixel tweaks helper searchbar removal 2.0.0.4 (flashed over 2.0.0.3 with magisk)
pixel tweaks 6.3 (apk) installed after uninstalling 6.2 version
Works like a charm! Applause for @eg1122
If I really have to find a flaw, I'd say that the dockbar still needs a bit more padding, top and bottom.
But heck, no, I'm really happy with my current config.
