Is your feature request related to a problem? Please describe.

In boards used for collecting ideas, feature requests, or backlog items, it is currently difficult to understand which cards are most important to users. All cards have the same visual weight, and prioritization requires manual discussion or external tools. This becomes frustrating when many users want to express preferences / prioritization or support for specific ideas.

Describe the solution you'd like

Add a voting system to Deck cards that allows users to vote (e.g. upvote) on cards.
Each card should display its vote count, and the deck should support sorting or filtering cards by number of votes (for example: highest votes first, lowest first, etc.).

This would enable team-driven prioritization of ideas, similar to >> see Additional context
