I find the dictionary function where you can look for example sentences and links to lessons really useful https://chinesepod.com/tools/glossary/entry/. What would be even better: Could the examples show the level of the lesson they’re from, or could this tool have a level filter?
This would make choosing new lessons much quicker and easier. I often use this dictionary tool when I come across a new word that I think will be very useful to learn (and to learn how to use it in more detail). I often choose new lessons to study based on this, but for example can’t do anything above intermediate so it would just save a lot of time if I could see straight away which lessons are the appropriate level.
