As the title said.
Requested in plasma-mobile/plasma-settings#17
I marked it as a draft because there is a small regression which removes vertical alignment of right icons.
call reconfigure in mobiletaskswitcher constructor to make it set the touch border.
this fixes the gesture-only mode in my setup, though one oddity remains: it only starts working after using the action drawer once - that may be an issue with my dev setup though.
This (partially) reverts commit 127bbdf653.
Only incorrect changes from Kirigami.Units.largeSpacing to
Kirigami.Units.gridUnit are reverted. Only Plasma.Units were buggy.
