I like how it shows all my tasks at once so i dont have go through each item one by ones which saves me time! It also has filters in place for different sections within your task list meaning you can find things faster than going though them individually when searching via keywords or date range etc..
There's nothing really bad about this program but if there was something they needed adding then we would certainly make use out feedback system - as always with any software product!! The best thing abut summarise its quick access anywhere anytime plus no need ot download an app unlike other programs suchas outlook where u might loose some data depending what version ur using (older versions).
