Hey! Thanks for the PR. I believe this could be just a simple component rather than module since there is no additional functionality there (liek vuex/router intercations etc).

Hi, @filrak,

So, it should be moved in the theme core component from the module?
Am I right?

[vishal-7037]

Hi, @filrak,

I've moved it to the theme component directory and seems working fine.

Please review it and let me know.

Thanks!
