@adibmbrk is this ready for re-review?

@MisRob This PR is not ready for review yet. The backend and frontend are complete, but I still need to connect them. I'll notify you once it's ready for review.

Ah good, thanks @adibmbrk. Take all the time you need, I just wasn't sure if we should re-review or not since there's many new updates.

Hi @adibmbrk, just checking in, are you still planning to come back to this?

[adibmbrk]

Hey @MisRob, Yes, I’m planning to get this done. I couldn’t spend much time on it last month as I was focused on my GSoC proposal. Now that it’s out of the way, I’ll be picking this up and finishing it soon.
