I hate it rearranges a meeting that I know it'd happen in a few hours, I plan my day accordingly, boom it's changed. That's frustrating. I worked at a big corp and people loved fully packed calendars with meetings. Wondered when they'd get any actual work done alone, without a meeting. My calendar was mostly empty except meetings that were crucial. Even though I was in a Principal role, new grads had more packed calendars than me. As a result, Clockwise moved most of my meetings.
