Gutenberg 2.6 is available for download and with it, comes a new way of sorting blocks. In addition to using up and down arrows, this version introduces the ability to sort blocks by dragging and dropping.
If you hover the cursor over the up and down arrows on the left side of a block, you’ll see a hand icon. Simply click, hold, and drag the block up or down below or above the blue indicator.
In my limited testing, I found drag and drop to be hit or miss. Sometimes, when I try to drag and drop a block, the blue line doesn’t show up.
The hand icon for the cursor is different for the top and bottom of the block. You can drag a block by hovering over the bottom of it but you can’t do it from the top.
Pressing enter at the end of a paragraph creates a new Paragraph block automatically. But I don’t know how to transform it into an image block. I’ll need to do more testing to figure out what’s going on.
