One very nifty thing is the new AI noise removal tool for recorded audio/narration. I'm not sure exactly how new it is, but the previous noise reduction tool was pretty limited. This AI version works a treat, and it's actually saving me a bunch of time exporting my WAV files to Goldwave to apply noise reduction. Then I'd usually export the updated audio files to MP3 and reimport them into Camtasia. Then I still had to manually replace the WAVs with the MP3s on the timeline. Now there's just no need for ANY of that, because I just select all audio files on the timeline and apply the one audio effect, and it's done. No muss, no fuss. And it does a great job, for the most part.

By using snagit I can easily decrease the file size of a picture making it easier to email multiple photos without exceeding the email size limit.

Same as the previous reasons provided above
