Absolutely. I love the work they have been doing on the backend, like PQ3 [1], but it just doesn't work for me when the Stickers and Emojis extensions on Mac leak several GBs of RAM and I have to terminate it several times a day to free up memory.
Another thing I dislike is that it stores the whole message history on the device. It's nice to have at times, but I send a lot of photos, which adds up in storage over time. I pay for iCloud, and store my messages there. Why does my Mac need to hold every single photo I have ever sent?
