Enhancment Goal: use "What's this?" more

This is a long term goal, we might reach it step by step.

Qt has a "What's This?" feature, which is like a advanced tool tip able to contain longer texts and instructions. We do not really use the feature, but especially for actions that are not obvious this would increase the usability a lot.

To add "What's This?" text to a widget or an action, you simply need to call QWidget::setWhatsThis() or QAction::setWhatsThis().

This is how it works

In the tool tip the user sees a hint to press shift to learn more

Pressing shift the "What's This?" text shows up

Another option is to go to first trigger menu "Help" > "What's this?" and then click on the widget or action you want to learn more about.
