Hi I am not sure if this is the right place to file a software improvement.
In Daedalus the download of the Cardano Blockchain is quite slow from Germany. The download speed on my computer was around 1.6MB/s but my total download speed is up to 8MB/s.
On another computer I run a 2nd Daedalus Wallet.
I think it would be good to support LAN syncronization to speed up the sync of the blocks between multiple Daedalus wallets within the same local network.
in linux you can find the topology.yaml file under .daedalus/nix/store-XXX-node-cfg-files/topology.yaml
There you can add more nodes the wallet can sync with.
The port of a running Daedalus wallet can be checked under Help->Cardano Diagnostics - Cardano Wallet port
yeah would be great to insert more remote node address via Daedalus, but at least you can edit the topology.yaml file
