BIP44 account usage recommendation.

Software should prevent a creation of an account if a previous account does not have a transaction history (meaning none of its addresses have been used before).

Software needs to discover all used accounts after importing the seed from an external source. Such an algorithm is described in "Account discovery" chapter.

Syrius v0.2.1 allows multiple account creation without having transaction history and does not have account discovery. In that regard it violates the recommendation.

The Ledger Live application combines both. It uses account discovery to select unused/used accounts to add. Depending on the chain, it also allows to filter on chain specifics like Native Segwit only addresses. Once an account is added, it can be removed or added to a favorites list.

Something similar could be done for syrius. Adding accounts will open an account discovery dialog in which one could traverse the account indexes until a suiteable account is found to be added to the active accounts.

Account discovery can also be used to quickly recover any used addresses or addresses with funds when doing a clean install or after a cache reset.
