Well, what I did is that I only use 1 wallet. However, I am going to generate multiple private keys thru bitaddress.org. I still have to download the webpage of the bitaddress.org and run it locally on my desktop unit. Disconnected the internet and enabled all firewall for all application without exception both incoming and outgoing for I am using windows OS.
From hereon, those generated private keys from the bitaddress.org, will be then be imported to Electrum. Thus, as a result I only need one wallet but had multiple bitcoin addresses.

I do not use the auto generated phase seed of electrum for I strongly believe in the near future a powerful computer will have  enough computing power  to crack and generate those seed phases and expose all the 16 different addresses or more along with it.

Having a private keys is edge since this is supported on most light client and full client nodes.
