I realized a problem while I was drawing, which made my drawing even more uncomfortable
When you draw it, it's an extension of the tree, but when you run it, you're climbing up from the bottom
So I would like to ask, in a later version
Can this aura be dragged

For example, when holding down a key, use the mouse to select a certain aura.
And then drag it to the other parts of the halo as a child, maybe there can be multiple operations?

I like this idea, though there is a tricky way to do this using scribing patterns:

The scribing patterns can be used in a circle that already has a pattern in it, which you could use like this:

1. Copy the spell into a Mirror, and then do the next steps in the mirror
2. In the circle you want to copy, draw the scribing pattern that turns the current circle into a subcircle of a new empty circle.
3. Use a trick to save the subcircle into an offhand item (NOT your original spell)
4. Now equip your original spell in your main hand and put the item with the copied circle in your offhand.
5. In the original spell, find the circle you want to paste the copied circle into. Draw a scribing pattern to either add a new subcircle to it, or some other pattern that adds an empty circle near it. In that empty circle, draw the scribing pattern that copies a spell fragment from your offhand item into the current circle.

I thought that would be more straightforward before I wrote it, but hopefully it is useful.

I don't believe allowing drag-n-drop would be respectful of the revision system. There is already a way, using Plagiarist's Revision and (Inner) Notulist's Revision to quickly move subcircles around the tree.

Oh, also, using the macro system you can remove the dependence on an offhand item.

Yes, macros fullfill this purpose.
