One of my biggest pains is the lack of reusability for:
- Screens I have built in an existing app: there is no efficient and qualitative way to "import" a screen into your PowerApps.
- Configured controls: a kind of code/control library, ideally across app, would be beneficial.
This is very important in the context of team work: It allows you to pre-configure (or even "brand") controls so that all of the team members can re-use the screens/controls/...
@GertVonck See if this helps: https://blogs.msdn.microsoft.com/davidni/2018/04/25/reusable-powerapps-control-templates/
You can curate your own set of useful templates, just go to https://patemplates.azurewebsites.net, paste your controls, and a link will be generated for easy re-use. It isn't perfect, but I've found it helpful in many occasions (full disclosure, I'm the author :)).
