Remembering Katia's older, longer lesson videos!

It's fantastic to see Katia still making such useful 'shorts' like 'Do you know this second meaning of MOONLIGHT?' and 'What's the difference?: TO NAME NAMES vs TO CALL SB NAMES!' They're always so clear and concise! But it also makes me think back to the earlier days of English Bits, maybe a few years ago. Does anyone else remember when Katia used to do those slightly longer, more in-depth grammar lessons or pronunciation guides? I particularly loved the ones where she broke down complex verb tenses or tricky sounds. While the shorts are amazing for quick bites of knowledge, sometimes I miss the deep dives. It's cool to see how the channel has evolved to fit the platform, but those longer format videos were truly foundational for my English learning. What were some of your favorite older English Bits videos or series?
