There is a PR for to add this support in Fenix, but this looks like a better intent processor to add ACTION_MAIN support. 🙂

[Mugurell]

Thank you @jonalmeida and @codrut-topliceanu !
I'm sorry I didn't see the previous work :-(
I'd propose merging this and closing the others when the issue is verified on Fenix.
