Currently the password generator, when using Memorable Passwords (which is the only thing I use because they combine high security and the ability to quickly type them out) and selecting the Capitalize (which should be spelled Capitalise, please, we aren't Americans here are we?) option the generator responds by capitalising EVERY word in the password. This has several negatives.

1. It is annoying as all **** to type such passwords into certain types of keyboards, mainly mobile keyboards, but it applies to any input method, it's way more annoying to hit the shift key for every first letter of each word than it would be to simply capitalise one letter or uppercase an entire word (my preference)

2. It only doubles the difficulty of brute force attacks if the attacker knows or suspects I am using Proton Pass, because they only need to test e.g. this1is2my3password and This1Is2My3Password

If you instead capitalised only one or a couple (but never all) words, then an attacker can't easily counter the strategy and ends up having to guess way more times per attempt than two.

If you chose to uppercase one or a couple (but never all) words, then you get the above, and it's also easier to type on mobile keyboards, because I can double tap the shift key and my mobile keyboard will help me.

My problem is specifically with point 1 here, the reason I use memorable passwords is so that I can easily type them if I should need to, but your approach explicitly makes it more annoying to type passwords if I choose to capitalise them.
