Feature request: Highlight cards with important labels

[Koc]

In our organization certain tasks or cards need to stand out more than others — e.g. urgent tasks, blocker tickets, or items requiring immediate attention. Currently, Deck supports labeling cards, but there is no built-in mechanism to visually emphasize cards marked as “important” based on labels.

Without this, many users must resort to workarounds (e.g. prefixing label names with “! ” or “High”, manually applying a special “urgent” label) or rely on memory.

Having a native “important label flag → visual highlight” feature would simplify user workflows and reduce overhead in managing priority.

Here an example how can it looks visually

This PR created to collect feedback first before an actual implementation (as suggested here #7218 (review) )
