Thanks @1ambda for contributing very interesting new feature.
I've play around with it and have couple of feedbacks.
### Couldn't make Spell as display system work
> The most important thing is, spell is not only interpreter but also
display system. Because it runs on browser. This enable us to combine existing
backend interpreters with spell like
So i tried following but couldn't make it work. Am i missing something?
### Configuring Display order of Spell doesn't make sense
Enabled spells are displayed in 'Helium' menu like below.
Which is designed to change display order of visualization package when
they displayed in chart selector inside of the paragraph.
As far as i understand, Spell does not have to be listed in the chart
selector and does not have to be listed there and change order. So i think
reordering should be only for 'Visualization' type package.
I think Spell can create another section just below enabled visualization
buttons, to list enabled spells.
### Display keyword of the spell
Each spell has keyword to invoke. For example `markdown-spell`'s keyword is
`%markdown`, `flowchart-spell`'s keyword is `%flowchart`. However, i couldn't
find these keyword anywhere but the source code.
So it'll be nice if 'Helium' menu displays keyword of the Spell type
packages.
### Example for example spells
If there's some informations or example that how to use (syntax, etc)
included example Spells, (e.g. in description section or somewhere) it'll be
more convenient.
