Explain the problem as you see it
Switching from other PKM tools can be sometimes tiring if we are used to using (( and [[ for references (e.g. in Workflowy (( for mirrors aka references and [[ for inline links aka inline references).
There is no way to specify right from the start of typing node content that we would like to put an inline reference in the beginning of a node – we need to use "@" and then Shift+Enter but sometimes the flow isn't as good as it can be.
Why is this a problem for you?
Differentation between inline referencing and referencing at the time of adding them can be sometimes problematic.
Suggest a solution
Converting:
(( to “@ as a reference”
[[ to “@ as an inline reference”
(with leaving bare “@” exactly as it is now).
