Addition of Cura Thumbnails

[SoLongSidekick]

Is your feature request related to a problem? Please describe.
My problem is that only Slicer thumbnails is currently supported and I use Cura.

Describe the solution you'd like
I'd like Cura Thumbnail to be supported.

Describe alternatives you've considered
Uh... finding a different plugin that does support it? I guess?

Additional context
I would just like to also second another user's request for the ability to re-order dashboard widgets, it's completely unusable due to illogical ordering as of now.

I thought we already did this, but perhaps I am misremembering, I'll take a look at it
