Homeyscript editing on mobile

Hi!

As a recently joined developer to Homey community I really enjoy the simple flow editor from my phone, and the advanced flows with homey scripts as well, based on the complexity of my needs.

However I found that it would be useful sometime to do a small edit to an existing Homeyscript from my phone or iPad.

Does anybody have a good workflow to do this from phone?
Can the homeyscript be hosted on github?

Thanks,
Csaba
