I especially want that for scheduling of recipes. Right now they run all the time, but there are definitely things I only want to run at specific times on specific days. For instance:
"If it's 7:00 AM [AND] it's a weekday [AND] the forecast is rain [THEN] Tell me to bring an umbrella" would be much more useful to me than getting notifications every time it's going to rain.
As it stands now with a single condition, I don't can't come up with much I want to do with IFTTT.
Slightly off topic, but has anyone figured out a good way to use IFTTT to do "If this AND this then that" type of recipes?
