The ease of use, how simple everything was to create new accounts/users etc., plus being able to easily see who has taken time off & when! I wish there were more features for this app but other than those few things i do like what we've seen so far with our implementation team at work!! Nothing negative yet - just excited as always seeing where these apps are going next :) We're solving problems associated wtih having too much unused paid leave available during busy times (i'm currently working from home). It's been super helpful because now people aren't wasting their own personal days or taking them without permission which helps us save money since everyone knows not take any extra unplanned vacations unless needed.
