Contributing multiple apps as one pull request or multiple

Hi, that's great! Sorry for not getting back to you sooner!

One PR with multiple apps is fine - but if you're changing existing apps I'd really appreciate one PR per app unless the changes are related. If there's an issue it makes it easier to pinpoint and roll back that way.

Additionally, some of them are not on their first version in my own repo. Can I leave it like this, or should I reset them back to version 0.1 before sending them in?

No problem at all about changing the version - just if it's not the first version it'd be really good to have a ChangeLog file.
