Since the ribbon is part of a CSS Flex group that goes from left to right, you can simply move it to the right side using the below CSS snippet:
.workspace-ribbon {
order: 3;
}
Simple as that Problem is, the tooltips still show on the right side, so you won’t see the icon tooltips anymore So you can get around that using a dirty hack that shows the tooltip “near” the ribbon, but it’s ugly looking and will show other tooltips in wrong places, too:
.workspace-ribbon {
order: 3;
}
.tooltip.mod-right {
left: 90% !important;
}
