It's something I have come to recognise when coaching older people (in particular) to use computers - every input requires positive feedback to show that the input has been accepted. Double-clicking is a case in point: the younger generation do not understand how difficult the elderly find it to hold a mouse still enough to achieve a double-click, or to have the right cadence on the button. I now teach right-click, then select an action from the drop down menu - each individual event results in a visible action (first click brings up a menu of options, second click makes it go away again, and then if it takes a while to implement the action at least you know you're probably not waiting in vain).
Scheduling a recording is similar: when you bring up the programme details and then select one of the actions, only a status output in very small text at the bottom of the panel tells you the action was successful, and this can be off the bottom of the panel's scroll bar.
