Accounts that have been created can be removed (hidden) from the Account Tab by using the "hide" function. For example, let's remove the XRP account from the D'CENT Wallet.
1) Click on the XRP account.
2) Click on 'Hide account'.
3) Click on 'Hide' to confirm the removal of this account from the D'CENT Wallet.
To remove a native asset account such as Ethereum, all the token accounts that are linked to this native asset account must be removed first.
To bring back the same account that was removed, simply re-add the account by pressing the (+) button from the Account Tab.
