On the other hand, I think that this feature based on titles could solve a problem raised several times on the forum: distinguish planned dates (in which I start working on something) from due dates.
One could imagine that todo's in a journal entry in YYYY-MM-DD format are scheduled dates. That the due dates are those that are written in the line at //YYYY-MM-DD
I would find this useful as it is a current limitation of Joplin's todo notes where you can only use the reminder as the due date. It would then be necessary to simply show both types of dates in the panel using different colors for example.
What do you think @SeptemberHX ? Maybe also @Imperial_Squid ?
