I wouldn’t mind a syntax like this:
!!info(optional custom title here)
blah blah blah content of the blockquote here
that supports multi-line
hopefully would support embedding code blocks as well inside
the content of the callout
!!
Another example
!!warning(Please don’t do this thing!)
This is the warning content of the callout
!!
The reason i like the exclamation point is it’s not common for people to start a sentence with an exclamation point, and immediately follow it with a word, so I don’t thing the syntax would be limiting for people, but they’re also VERY accessible with quickly typing, and it sort of indicates by being an exclamation point what it’s doing (ie, bringing more attention to something)
By using two exclamation points, I was thinking after typing in the second one, you could pop up a list of selectable types to choose from, kinda like how the universal coupler looks and works.
I mostly want to make sure they’re easy to add, even on mobile, and easy to remember the syntax for them. I found the blockquote syntax within backticks very hard to remember on obsidian, so i’d hope for a bit of a better solution than that, personally.
