Template Updates for vNext

[FriedrichWeinmann]

Will work on adding new features to templates, for some revamp / upgrade.
And since my memory is as horrible as it is, I write down my ideas somewhere I'll find them again.
Feel free to add your own proposals as response, happy to include ideas from the hivemind :)
