I love how easy this software makes reading my documents at work! It's so simple yet very effective with its features such as "read later", which allows me access from anywhere even when offline (no need wifi).
Sometimes you might get stuck while trying out new feature but there are tutorials available just like what we used during our training session where they teach us step by steps about each tool/feature before hand if needed - great customer support too!! Easy enought navigation through multiple files within one folder- no issues here either!
