I've just pushed build 114, which improves the experience of the spell editor.
Before, you could only grab words from your word-pool at the bottom. Now you can grab and move words in the spell itself.
Dragging a word from the spell and dropping it into empty space can be used to remove words from your spell. You can also do this to easily peek at the names for the inputs if you have forgotten.
Grabbing a spell word will also grab all the words connected below it. This helps refactor or rework your spell more easily.
