Password Gen. Memorable Passwords

Yes I saw that but the current way it mix number and separators make the readability / separation a bit hard.
For Example:

• Orange0nix3214_tree1lemonade vs
• Orange-nix:3214_tree.lemonade

Would be great if there were an option "Random Separators" which use a random of "-_.:#@!?" if you need to really type them in a console in a bad situation like on a rack or something it is really helpful.

e.g. Like this draft:

Seperator: Like now, +add: Random Separators
Capitalize: Not on/off add a choice of mixed random Capitals instead of a full Word
Add Numbers: Add one number block instead of one word

Some Devices nowadays have very strict requirements for password "security" e.g. some modern nextgen firewalls I use have this:

min 12 Chars, cannot contain user name, at least 2 of each: number, lowercase, uppercase, special

If the password is hashed correctly t and follow normal best bractise his shouldnt improve security much but well it's their requirement which makes the use of memorable passwords sometimes harder.

So in a Ideal world I would like to have those requirements met and have a password one can still type :)

Thank you so much.
