Yes, it's possible. I have it set to 2 seconds and find that more suitable for me. /usr/lib/qt5/qml/Sailfish/Silica/RemorseItem.qml /usr/lib/qt5/qml/Sailfish/Silica/RemorsePopup.qml In those files, find the timeout numbers (two in each file; by default the value is 5000) and change them to 2000 (to get 2 seconds instead of 5). RemorseItem.qml affects remorse timers that happen "in place" (e.g., deleting an email) and RemorsePopup.qml affects timers that appear in the top part of the screen (e.g., deleting an app in Launcher). (Don't set it to zero though (to disable the timer altogether), it won't work (at least in some cases)).
