VueJS Progress

[Biont]

Hey since the PR is now merged into a separate branch, I wanted to create a new place to discuss changes for the upcoming JS rework.

I really really hope I can find the time to work on this soon. In the meantime, can you, @e-alfred please sum up what would be hard criteria for you to merge the branch? And can we please break it down to some "minimum viable product" kind of thing? The discussion in the old PR had a lot of nice-to-haves mentioned and I'm sure not everything discussed is needed for the very first step.
