feat: filler between blocks

 Tell the engine if the block should be left or right-aligned.
 
-### Vertical offset
+### Filler
 
-Move the block up or down x lines. For example, `vertical_offset: 1` moves the prompt down one line, `vertical_offset: -1`
-moves it up one line.
+When you want to join a right and left aligned block with a repeated set of characters, add the character
+to be repeated to this property. Add this property to the _left_ aligned block.
 
-### Horizontal offset
-
-Moves the segment to the left or the right to have it exactly where you want it to be. Works like `vertical_offset`
-but on a horizontal level where a negative number moves the block left and a positive number right.
