File i-130 online?

[USC-husband]

I noticed a new button on the USCIS website that allows people to file form i-130 online!
What do you guys think of this?

https://www.uscis.gov/i-130

Has anyone here filed their form i-130 online yet?
Is this better than filing the actual paperwork through regular mail?
How could concurrent filing take place with this option?

1.- I haven't read any posts about this
2.- is better because the filing is instant, they will ask all the information needed, upload required/additional documents and can pay the fee with a credit card right there (just helped someone file N-400 online, it was easy)
3.- don't know if it will allow concurrent filing if it does, the system will ask you about other required forms (I doubt this is the case but will only have confirmation when someone fills the information)

If you want to try, you don't have to submit if it doesn't give you the option to the concurrent filing. Maybe you can file the other forms by mail once you get the I-130 confirmation, no?
