When in the editor, if I scroll across to view columns in one sheet/table, all other sheets/tables move to this position too. The expectation is that each sheet/table is independent of each other so that you can be viewing the first column in one sheet/table, and the "x"th column in another and be able to flip back and forth without it losing your place.
mmm, I noticed this as well.
But I actually quite like it, because more often than not I want to be working at the end of a table on those columns that have been most recently added.
So I’d consider this a nice feature, rather than a bug
