Since a couple of updates ago, the Quick action toolbar only has 1 row. I have the advanced mobile toolbar plugin, and I set the width to 2 rows. The bar occupies the whole 2 rows width, but the buttons remain arranged in only 1 row.
I am a bit confused. But I know for sure that the bar with the quick actions that yiu can see in the screenshot used to have 2 rows, until a few updates ago. So something has changed somewhere, and it is making my life a bit more difficult.
It is the one configured here, in the screenshot, so I guess it is the Obsidian native one
