I manage my work-related tasks on a personal board. However, if a co-worker assigns a card on another board to me, it won't show up on my personal board, so there's a risk I might forgot about it.

Describe the solution you'd like
Similar to how users can define a "Done" column, I'd like to be able to define a "My tasks" column in which all cards I'm assigned to across all boards show up. Maybe with the exception of the ones coming from the board the column is defined on. But since I don't assign myself to cards on my personal board, it doesn't matter to me, and whatever solution's easier to implement would be fine.

Describe alternatives you've considered
A "My tasks" board instead of just a column would be even better. Maybe there could be one board per user that would be created by default and contain all cards assigned to that user. Not sure whether that's easier or harder to implement than the column solution, though.

Additional context
At my previous job, I used Asana's "My Tasks" (https://help.asana.com/s/article/my-tasks) in board view to organize my work, so not having something similar in Nextcloud Deck feels limiting to me.

Start by reviewing how Deck currently represents boards, columns, cards, and assignees, then compare the proposed personal column and personal board alternatives. Done means a user's assigned cards from other boards are collected in a clearly defined personal view without losing their existing board context.
