As someone who has a lot of schedules going, and at a pretty rapid pace, a big issue I have is that even though I know that you can go into the settings of a schedule to freeze it, on days where I suddenly have major life events pop up (death in the family, traveling, etc) I do not have the energy to individually go into the settings of each schedule and freeze all of them and then individually unfreeze them when I get back. Then, when I do come back from whatever life event has distracted me I'll have like 1,000 terms to catch up on and I get overwhelmed and don't want to study at all. I know this is partially my fault for setting so many schedules but I really do feel like it would be useful to have a big "I'm Taking a Break Today" button on the homepage that would freeze all of your schedules for the day and then go back to normal the next day.
I have some plans for exactly this, and related functionality! It'll get rolled out in stages, but if you're interested, make sure you are signed up for experimental feature announcements (menu > settings > experimental) so you're made aware of what it's up for testing!
I cannot say exactly when it will happen, but it's near the top of my list.
