A new repo qtum-electrum-new has been built to add qtum-related features to the latest code for Bitcoin electrum.
Lesson 1: Third-party Electrum servers can link your two transactions together. This can be avoided by running your own Electrum server, supported by your own full node.
Note: Electrum-XZC is derived from Electrum and uses different seed phrase criteria, so it cannot be imported.

The Electrum team has also been developing other features. Electrum Wallet users can view the full release notes here.
Electrum-LTC is a simple but powerful Litecoin wallet. Like its predecessor, the Electrum-Bitcoin wallet, the open source wallet is available on GitHub and anyone can view or upgrade the code.
Lightweight Bitcoin Wallet Electrum announced that the next version will support Lightning network payments, implemented with Python, an electrum network node where wallet users do not need to run Lightning network nodes themselves to make payments, and electrum's Lightning network nodes have now been merged into the Electrum master branch.
It's not hard to run your own Electrum server and point your wallet to just use it. This restores Electrum to the point where it has the same privacy and security attributes as the full node, where no one else can see the address or transaction that the wallet is interested in. Electrum then becomes an all-node wallet.
At this time, the SPV-based Electrum wallet became the new favorite of Bitcoin players. Especially for small partners who are new to Bitcoin, editors recommend using electrum wallets.
