I certainly would want everything to be accessible more quickly… but with @ for block links as well, will it slow down the original inline links? Where and when do you picture the selection of insert style (block or inline) to take place? Maybe another symbol for block links?
I’d just like to mention how Tana does this or something similar to this. When you use @ at the beginning of a node, you transclude the whole block. While if you use @ inside the block, you would do an inline mention similar to what AT does now.
The way this could be implemented in AT is to use @ for /link commands when you use it in an empty block, and keep the same functionality for inline mentions.
