1) Does electrum generate the starting addresses deterministically?
Yes.
2) Can i set the initial seed of the wallet, because i dont know how the internal RNG performs, to make it more secure
No. Electrum generates seed with enough randomness to protect you.
3) Can electrum be used to store big amounts of bitcoin, in cold storage, safely? (Due to Armory becoming intolerably big over 100GB now)
Yes.
4) Is electrum's watchonly wallet with offline private key storage perfectly secure (doesnt leak private key when you transfer signed file)
Yes but if your computer is insecure, that is, contains malware, there is a possibility for a theft.
5) I think electrum should have 3x verify/type your password at the beginning, instead of 2, to make sure you enter it correctly
I think 2 times is enough.
6) Electrum's fee/kb seems silly, we all know that a fee of 0.0002 is now the convenient, /kb doesnt matter
You are wrong. "/kb" does matter. If you send a transaction with big size, 0.0002
BTC may not be enough. After all, miners choose the transactions and they prefer transactions with higher fees.
7) Can you please implement an option so that i can close the Console window, i`m sure 99% of users dont need that
You are wrong. Console windows are useful.
8] When i restore the wallet from seed, is the wallet itself being stored on some server, from where it retrieves it, or its is only an algorithm that remakes the wallet?[/b][/color]
No. Electrum is an HD wallet. When you create a wallet, an extended public/private pair is generated. You only need to store it.
9) Is electrum's debian/linux wallet bug-free? Does it work in debian?
I don't know about Debian but linux works well and I guess Debian too.
10) Can the seed regenerate the wallet entirely as in 100%, without any additional info (i suppose the password is still needed to unlock it after) ?
Yes, it will generate same receiving addresses and change addresses.
11) Perhaps after the performance/security updates are reasonable, have you guys thinked about a more user-friendly outlook with nice buttons, and theme, to make this wallet more user friendly.
If you guys answer to my questions, suggestions, then this wallet will become the NR 1. best bitcoin wallet, with all features included!
I don't know how answering your questions make this a "number one" wallet with "all" features.
Btw, you can use nobbc code, if you don't want a bbc code to be parsed. Eg:-
