Allow a preworkout change to timers (like 2 minutes for primary lifts and 60 seconds for accessories). Having to click it down for three minutes for every exercise, every workout is an annoyance.
You can also edit your exercise and set the default rest time for it. Then you don’t need to adjust it during the workout.
The default time per exercise doesn’t always seem to “stick”. Even after setting a default to 2 min for that exercise, it is sometimes still 3 min during a workout. Maybe a bug(?)
A universal timer setting would also allow changes for the competition lifts. Right now, the rest timer for those is not editable, it needs to be done during the set.
Setting this in one spot is way easier than setting in each of the dozens of individual exercises. Maybe I am in the minority, but I’m rarely resting for >2 min.
