That would make it easier to view everything. ### 5/5 — Game Changer. *2025-03-25* I’ve been with Glass as my main To Do Planner, and I just love the simplicity, practicality, and ease to forward the events to the later day… I procrastinate a lot, but this allows me to either reschedule with one swipe, or just schedule a repetitive events. Glass is a Game Changer because it’s different than your running list or your daily do to, it’s incorporating everything in, so you can tell how much time you will need… ### 5/5 — Glass is back! *2021-08-07* Been waiting for this app to be updated for a long time!
