On large dashboards it is difficult to move around panels with the drag&drop technique.
Would be nice to have an alternative "more robust" way to do it.
An example would be to have four arrows near the already added "remove panel" and "edit properties" that move the panel in the appropriate direction if pressed (jumping one panel at a time if vertical direction and one column at a time if horizontal).
even sometime seems to me not properly working
If this isn't working properly, please file a bug report with complete reproduction steps we can use to reproduce the issue. See Contributing Bug Reports.
I removed the part of not working properly, since as you reported I should make a better reproduction description.
I left the rest of feature request.
I don't plan to implement the rest of the feature request. Assuming drag and drop works correctly, I think this operation (reordering panels) is rare enough that using it is reasonable without introducing the additional complexity of duplicate controls.
Among other issues, arrows are, e.g., ambiguous in this case:
... | | | B | +----------+ +--------+ +----------+ | A | +--------+ | | | C | | | +--------+ +----------+ +----------+ +--------+ | | | D | ...
If you click "Move Right" on "Panel A", does it move between panels B and C or between panels C and D?
Issues like this would be more complex on more complex layouts, particularly if we introduce additional layouts in the future (see T6444).

For me would not make any difference, since with another simply up or down will (reliably) soIve the problem.
Moreover most probably when I change the column (as I was) I would position it even more differently (requiring more ups or downs).
