@catarak What is the behaviour we're finalizing? Can you please list down the spec in a bit detail?
I can start working on it if it's in priority.

@MathuraMG is this feature included in #508?

[MathuraMG]

@catarak - this is not included in #508 , this will be along with/after #503

[catarak]

got it! i guess this issue and #503 are dependent on #508?

[MathuraMG]

yep!
