Seriously I LOVE 1password. I moved away from LastPass to it after reviewing some of the OSS offerings. I have not found a more feature-complete (and pretty for that matter) alternative.

One of the my favorite features that I cannot find in other password managers it the built-in 2fa support. Click to login to a 2fa enabled site and it copies the code to your clipboard so you just paste and voila at the next screen. Perfect!

One example is how 1password hijacks the ctrl+F key combination.

So, if I have a long secret, perhaps a config section, I have to manually copy and paste it into a text editor in order to properly search through it.

Same. We have it at work, but 1Password's UI is the reason I use it at home as well.
