Possibility to add multiple apps from the crowdsourced repo at once and small UI annoyance.

[Sanzium]

Hello.
First of all, thank you very much for the awesome project.

I would like to suggest a feature/enhancement to allow adding/importing multiple app templates from the crowdsourced repo at once (sorry if I should have posted in that repo instead of this).

Related to this, there is a small inconvenience in the UI that is the fact that the button to add a crowsourced app config gets covered for a few seconds after adding an app from there:

When trying to add multiple app configs, it may be a little annoying.
It's a minor thing, but if have time and consider it worth it, maybe moving the buttons a little up would be better.

Thanks!
