After using the new version a little while I have to say that I hate typing my over 10 letter password every time I want to use 1password.
You should at least leave the option the choose between the original master password or the good old 4 number password.
I loved in the last version that I "only" had a 4 letter password and then
an other password to view the actual password details.
Now with a 10 letters pw I make a mistake every time I try to get my password
