feature: Render footnotes

[einarpersson]

Is your feature request related to a problem? Please describe.

I use footnotes in my notes and it would be nice if it would be rendered by this wonderful plugin.

To quote this post:

For a little while now I’ve been using footnotes in Obsidian. I think they’re a bit of a “hidden feature”. They’re in the documentation, but for some reason I rarely see people use them.
...
[using footnotes] allows your ideas to flow out of you more naturally, and you don’t have to worry about restructuring your note to fit previous modes of thought.

Also note that Github now supports footnotes in their markdown, so this is not "just Obsidian".

It would be a great addition imho which shouldn't be too hard to implement, I think?

Thanks again for a great plugin!

Describe the solution you'd like

Sam[^1] is almost two years old.

## Footnotes
[^1]: Sam is my son 

should be rendered as

Sam⁽¹⁾ is almost two years old.

## Footnotes
⁽¹⁾: Sam is my son 

Paranthesis have to be used instead of brackets as (to my knowledge) you can't use brackets in superscript utf8 (or?). But I think paranthesis are alright.

Describe alternatives you've considered

Just having it as is.

Additional information

• Perhaps there are some configuration options, but as a first step I propose just implementing the above.

• Note that the main obstacle with footnotes is creating / formatting / maintaining them, but this is not the scope of this plugin. There are other plugins that can help with that.

• Note: Only caret symbols [^....] should be rendered this way, as to not interfer with other things

Thank you for the kind words, glad you are enjoying the plugin!

Added this feature here: 634acd5

LMK if this is what you had in mind!

That was quick! Yes that was what I was asking for. Thanks a lot!

Hi - sorry for reopening this. It works well, but after playing around with it a bit I'm wondering, if it is not too much hassle, if you could either remove the paranthesis or add a config / option for that. The paranthesis adds unnecessary spacing which I guess is due to monospace font.

Just having the superscript would also make it less noisy

[MeanderingProgrammer]

Sure, updated the behavior here: 1b5d117

The prefix and suffix are now configurable for footnotes. By default both are set to the empty string. I agree that monospaced fonts make the superscripts look strange in general.
