Allow multi-chain account injection
Feature request: For certain chains, likely many common good chains without native tokens such as Statemine, an account is meant to be used in the context of many chains. When an account is selected for use on e.g. Kusama, it should also be injected into a select set of parachains. I'd start with the rule: if it uses KSM as its native token, the same accounts that were selected for the Relay Chain should also be injected into the parachain.
Right now, I had to select "use on any chain" for accounts that I only want to use on Kusama/Statemine.
This is a long-running issue in both the apps UI and the extension. (It will be addressed in the latter first, where it was first logged).
The selector is to allow for selection of multiple chains allowing the keyring to match on multiple genesis hashes, instead of the one it currently uses.
As to when? Sometime. It has been hanging about for quite some time already.
This issue may have some relation to an issue we are having at ChaosDAO as we are deploying a 12 party multi-sig across multiple chains. Our process was to add each individual to our address book, select create multi-sig button, add parties and threshold. We repeated this process for Karura after which step we observed an issue where our address book was wiped out on the previous chain (Kusama). Some report the Mutli-sig wallet also disappearing.
Having a feature that let us distribute our multi-sig across all the chains and setup the existential deposit would be incredible.
