A feature that lets me stop for a day and still keep my completed daily streak would improve my experience with Memrise greatly.
I know some courses are shorter than others, some are community courses and some are official, inevitably active courses will have different daily streaks as you complete some, continue others and start new ones. A universal streak freeze might be difficult to implement, but man it’d be so helpful.
Streaks are huge for gamification and are a great motivator. Some days are too busy, some days you are too tired to practice languages. An option for an organized rest day would be great. It’s so much easier to get into practice after an organized break, instead of skipping months because of a lost hundred day streak.
