I've used Boomerang for Gmail since it was first released, and I couldn't live without it. The ability to "snooze" emails until various future times is indispensable. If you rely on your Gmail for work, or even if you are a heavy Gmail user in your personal life, after using Boomerang for a day or two, you won't know how you ever lived without it. It is probably the most useful feature in my entire workday.

I just upgraded my Mac to Catalina from Mojave. Previously, Opera had great support for smart cards (also known as CACs or PIV). However, the update in OS seems to have broken this support, as Opera no longer seems to "see" the smart card in the reader. Chrome and Safari continue to work fine with the card. Any ideas?
