While typing in the quick add input, recognized Quick Add Magic fragments should be highlighted live (like Todoist does) for dates (“tomorrow at 5pm”), repeats (“every week”), labels (*), projects (+), priorities (!p1) and assignees (@).
Currently there’s no feedback about what Vikunja will parse out of the title until the task is created, so misparsed fragments (a date that wasn’t recognized, a label that will be created, etc.) are easy to miss. Highlighting gives instant visibility and also makes the magic syntax easier to discover.
