We need to implement some new methods.

@amihaiemil this is your task now, please go ahead. Deadline (when this ticket should be closed) is 2021-08-26T14:59:48.701538.

Estimation here is 60 minutes, that's how much you will be paid.

Remember, you don't have to solve everything in this ticket - you can solve it partially and leave todo markers in the code, which will become future tasks.

If you have any questions don't ask me, I'm not a technical person. Open new tickets instead.

If you don't have time or simply don't want to work on this, you can always resign.

@amihaiemil please keep in mind that manual assignment of tickets is a bad practice and it is discouraged. Next time, please let me elect the assignee.

@amihaiemil Don't forget to close this ticket before the deadline (2021-08-26T14:59:49). You are past the first half of the allowed period.

@amihaiemil thank you for resolving this ticket. I've just added it to your active invoice. You can always check all your invoices and more on the Contributor Dashboard.
