Library items: reorder, new sorting by drag & drop#108

Would be great and a lot easier to work with a lot of animations in Motion.page if the ordering of the different animation in Library-Sidepanel could change.
So the animation would be listed by appearance/use on the page or kind of grouping together.
ALSO and especially when a new animation comes to the page, after an other animation a lot further down on the page was created.
I can NOT find any solution to change the ordering/sorting.

If there is some built-in solution that I can not find, I would be pleased to get some hint in the right direction or helping hand for reodering.
